    GM part number for door latches

    Looking to buy some NOS door latches for both doors on my '77 K15, but I'd like to search for them by the correct GM part number so I know I'm getting the correct ones. I've seen them listed by several different part #s on eBay, so it's kinda confusing. Does anyone know what they are for each...

    15x10 with 3.5" backspacing?

    I'm thinking about getting some new 15x10 US Mag Indys for my '77 K15. 4" BDS lift, 35x12.50 tires are being used. These seem to only be available with 3.5" of backspacing. Does anybody know if that will work OK?

    Western Bullets

    Does anybody have a picture of a set of Western Bullets on a K10/K15? I've got an opportunity to buy a restored set of 15x10s, complete with center caps and lug nuts/washers. Interested to know if the original style flat caps will clear the hubs?

    NP203 boot

    Has anybody had any luck with a universal leather shift boot for their 203 that works with the stock trim ring, or comes with one that will work? I'd like to retain the shift plate if possible, but I can get a ball with the pattern instead if I have to. I got the one from USA1, but it just...

    Door wiring conduits

    I'm doing a power window/lock conversion on my '77, and the truck has no door conduits, nor the holes where they would go if it was so equipped. Can someone with a '77-80 truck take a pic and some measurements for me so I know where to drill the holes in the door and the front of the cab? Thanks!

    Dakota Digital RTX gauge cluster

    Has anybody with the Dakota RTX series gauge cluster noticed that the gas gauge is not centered in the circle like the other 3 gauges are? Mine is offset significantly to the left. I just noticed it now, ordered back in June or July, so it's probably too late to get them to do anything about...

    Fresh Air vents with factory A/C?

    I've got a 1977 Sierra Grande with factory A/C. Is there supposed to be a fresh air vent assembly on the passenger side on this truck? Can't seem to find any solid info on this. I'm seeing the valve assembly on LMC and USA1, but I can't seem to find the pull handle that would open/close it...

    Kick panels with 6.5" speaker pods

    Are there any good brands of kick panels with speaker enclosures for the '73-80 trucks with factory a/c? That will allow the parking brake to be used? The ones I got from USA1 say they're for '73-87, and they look absolutely nothing like the kick panels I've got now. Unfortunately, mine are...

    Headlight bezel restoration

    Has anybody restored their original metal headlight bezels for the '73-78 trucks? Mine are missing the argent paint that should be on the recessed part around the headlight. Curious as to what everyone has done to prep the surface, what primers and what paints are ideal for this. Thanks.

    Stock radio mounting

    My dash has been hacked... horrendously poorly... for a now missing DIN style radio. Does anyone know if the factory style aftermarket radios out there need the metal structure to mount, or do they just attach to the instrument bezel? I'm looking at the USA-740 from Custom Autosound. Really...

    Did the NP203 change internally between 1974 and 1977?

    The only shop manual I can find for the NP203 that goes into great and specific detail with step by step procedures with photos is this one https://ck5.com/forums/threads/np203-rebuild-guide.341563/ but it's for a 1974. Are the procedures and tools required the same? I've found all of the...

    np203 shifter

    Does anyone know if there is a replacement shifter or a rebuild kit available for the stock NP203 shifter? Offroad design is "temporarily" out of stock for their twin stick kit, and from what I'm reading on various forums and groups, they have been for years now. Not looking like they're going...

    OEM grille material

    Anybody know what the factory original grille and headlight trim was made out of on these trucks? 1977 specifically. Best I can tell is it was plastic, but that seems highly unlikely? The headlight trim I have now is metal, but the grille is a plastic "billet" unit.

    USA made sliding window assembly?

    Anybody know if there are any small businesses or other companies selling an American made sliding rear window assembly? There's gotta be someone out there, as popular as these trucks are. Not gonna put any of that ***** crap on my truck lol. LMC is not made in USA, already tried there. I'd...

    How to tell if my NP203 has been converted to part time?

    Got a '77 K15. It's got the NP203, at least it should. I've got the low lock, low, neutral, high, and high lock on the shifter, but the truck has locking hubs. I've been driving the truck in high with the hubs unlocked, is that a good indicator that it's been converted? I have the truck up...

    Steering column

    Question about the steering columns in these trucks. I've got a '77 GMC K15 4x4, and am looking to get a Flaming River steering column, or possibly Ididit. Flaming River offers 2 different ones, one doesn't give any specs and the other says it's for a 1" 48 spline output shaft. Ididit only...

    1978-80 dash trim on a 1977 dash?

    I'm re-doing my interior with stuff from USA1, and they don't have dash moulding (the piece that goes over the glove box from vent to vent on the passenger side) for the 1977 trucks. Anyone know if the '78-80 moulding would fit my '77 dash, or should I just buy a '78-80 dash from them? I'd...

    Wiper differences

    Anyone know what the difference is between the '73-77 and 78-87 wiper systems? I got a painless harness for my truck, and it shows them as being different. It comes pre-wired for the '78+, but provides instructions to add different connectors for the older trucks. Would it be advisable to put...

    A/C blower always running when key on

    Good evening all, and happy fathers day! While trying to find a switched 12v source, I noticed that my blower runs the entire time I have the key turned on (2nd notch, just before it cranks). Anybody know what could cause that? 1977 GMC K15 with factory air. I looked at all the connections...

    Radio wiring

    Anybody have a wiring diagram for the radio in a '77? My truck has no radio now, and the wiring has already been cut so I can't just get an adapter. Thanks.

    raising seat height

    Hey all, Question about raising the height of my stock bench seat. I had forgotten just how uncomfortable the driving position is in these trucks lol. I gotta sit with my legs practically spread-eagle to drive this thing because the seat sits so low. I could wear a stovepipe hat in this...

    Blower motor

    My AC blower doesn't really blow that hard in my 1977. Could this be a ground issue, bad switch, it just a tired old motor? Factory AC truck. Thanks.

    Side tracking

    My truck is side tracking. The back end looks like it's offset to the right while the truck is driving. I attached a pic, but it doesn't really show it too well. My friend had a similar problem with his '74, and it was either swapping the rear leaf springs left to right, or swapping one of...

    Power door lock conversion

    My '77 GMC K15 does not have power door locks. I would like to convert it, but the only kits I can find are universal. Is there a kit designed specifically for these trucks that is plug & play with the factory wiring harness and compatible with the stock door switch? If not, are any of the...
