    1980 K10 Stepside filler pipe housing

    There isn't much aftermarket support for stepside fuel filler parts. You will probably have to find a used one. 1980's used filler doors and the filler doors were the same ones used on fleetsides. You might be able to adapt the filler housing from a much more common fleetside.

    Anti-Theft and Post-Theft devices

    Kill switches pre theft , AK47 post theft. Low lifes attempted to steal my camaro twice, factory VATS prevented them from getting it. They attempted to steal my NBS 1500, kill switch saved it. I'm considering adding a chipped key and homemade VATS system on my current truck.

    Stance

    Personally i like dead level or a slight forward rake. Sometimes the rear shackles have more than 1 position maybe you can adjust it there, other options would be an add a leaf or lift blocks/spacers.

    Fuel Gauge Issue

    I can't say for sure on the 5 volts but i think that's probably rite. If you ground it and it goes to empty and open it goes past full the gauge is good. 1/2 tank should read 44 ohms. sounds like a sending unit. For Truck Years: 1967 - 1990 The Fuel Gauge Needle Should Point to: Left Line...

    Which fuel return is best?

    Does it bubble with the engine on or only after it is shut off? I would expect it to bubble with it off and no fuel pressure. If your worried about vapor lock that happens on the suction side of the pump not the pressure side. If you do run a return line from the carb make sure your pressure...

    What is this vacuum thing?

    it's a thermal vacuum switch that switches between manifold and ported vacuum for the vacuum advance. To the best of my understanding on this, in theory you run on ported causing the engine to run hotter (late spark at idle) as the engine reaches operating temp or possibly over operating temp...

    Cleaning up my wiring. What does this plug go to?

    Ported vs manifold is an in depth subject. The short version is generally for performance manifold is prefered and was how it was originally done back before the mid 70's. In the mid 70's auto manufactures were trying everything the could to reduce emissions. running retarded timing at idle was...

    Turn Signal and Horn Broke

    probably replacing the switch assembly #12 will fix it all. since the horn was part of you problem you might at least have the horn ring #7 on hand just incase it broke to. There is a tool to compress the spring #8 under the steering lock plate #6 , I have always had good luck using a big...

    Need direction as to where to buy this

    i would try your local parts store maybe napa. if not here's a listing looks to be correct https://www.carolinaclassictrucks.com/78-87-GM-FS-Truck-Prop-Valve.html Switching from cast to brass shouldn't be an issue. I have seen these fail so rarely I would use one from a pull a part to.

    Are you using a test voltmeter or just the dash gauge?

    Rear sway bar

    One from a S10 blazer might work. The width lines up with the frame rails.

    Under dash wiring

    it's a 77 that didn't originally have a delay. The delay and wipers motor came from a later model donor 85-91 and required some rewiring.

    Alternator wiring?

    Gauge is a completely separate circuit and has no effect on the alternator. the D+ on a SI10 , SI12 is the equivalent of the L terminal on a cs130. The D+ or L terminal is wired in one of three ways. 1. wired to an ignition source through a resistor wire (there is a special wire that has...

    Need some help with tire fitment

    (15x8) 245-60-15 (15x10) 295-50-15 this keeps the front and rear the same diameter and matches the wheel width. was lowered when i got it i think it's only 2.5 front and 3? in the rear drop. wheel offset will affect how they tuck.

    Fuel gauge and valve questions

    If you suspect the valve , disconnect it and run a jumper wire between a-b then c-b , also check the weather pack connector to see if the b terminal is damaged, Tug on the B wire see if it pulls lose from the connector.

    Diagnosing a transfer box noise ?

    First check the transfer case fluid level. Some of the later ones would rub a hole in the case and loose all the fluid.

    What to do with gas tank vent when all emissions components are deleted?

    I believe an 84 is a screw in gas cap, if so i dont think they sell a vented screw in cap. If it uses a cap with 2 ears on it you need one from a 73-74 that didn't have an evap system.

    LMC Truck Battery tray doesn't fit

    I see your pretty young. This is a common problem with all auto parts and the older the car or truck the worse it is. There are several reasons parts dont fit. Manufacturing changes, there could be several versions of the part you want and you simple ordered the wrong one. Sometimes...
