    LE9 305 w ESC Performance upgrades '86 k5 Blazer

    If you start having intermittent starting problems that you can chase down to lose of spark, I would look at the ESC. You can buy a $20 bypass loop cable on ebay to disable/bypass the ESC, and leave all the ESC stuff in place. Check the timing after disconnecting the ESC, it will probably be a...

    FB Marketplace find near Austin, Texas: 5 aluminum K10 wheels $50

    The centers are the same as the rally wheel center caps. All rally centers have a hole in the center under the sticker. The hole is perfectly placed to mount these 3" bullets from ebay. I had to buy bolts the correct length, used lock washers, and put epoxy on the bolts when i screwed them in...

    FB Marketplace find near Austin, Texas: 5 aluminum K10 wheels $50

    I think only the hoops are forged, not the centers on the earlier ones. The hoops on the inside of the forged ones are MUCH smoother. here are the only markings i could find on mine.

    FB Marketplace find near Austin, Texas: 5 aluminum K10 wheels $50

    I've seen them listed in Sales Brochures as early as 1976, but as a dealer installed accessory. I never saw them very often until they started using them on a lot of Vans, Suburbans, and Blazers around 1987. It is my understanding there are two versions that look basically the same from the...

    Nice squarebody on BaT

    Those floor mats are different than my 83. Those look like the repops Holley makes. Maybe those are right for that year???? I don't know.

    What have you done to your square lately??

    Wired up the USB outlets on my new console from Smokey Mountain Classic Seats, eventually i want to hard wire it into the fuse box. But I put a cigarette lighter plug on it for the meanwhile. I also made a foam rubber mount to hold the console in place without having to screw into the truck...

    What have you done to your square lately??

    I had to do TWO sets of belts. Take apart the replacement ones, remove covers. Take apart my old ones then switch covers. I was doing the 3rd cover before a had a spring go flying. It WAS quite surprising. Ha ha . But yes, it is incredibly tedious.

    What have you done to your square lately??

    i found some matching seatbelts at the Nashville C10 Nationals in October. On the new set the covers were perfect, but the belts were stained and badly sun faded. Whereas my old belts are great but the plastic covers were disintegrating/stained. I got the covers installed yesterday. It was a...

    Huck's daily - 2005 Z71 crewcab

    I've been looking for a 2wd CCSB from 2004 to 2007 (classic) for months and months, preferable GMC (and not gold or silver/gray ), there just aren't any, at any price reasonable or unreasonable.

    Starter drag when engine is warm

    I'm having an intermittent problem with my truck. When the engine is cold it starts great. But if i try to re-start it after driving 20mins or more, the starter drags then will generally start. One mechanic said it was the battery ground cable. so I replaced the ground cable with a 2 gauge...

    I saw it at the AMD booth too, but didn't think it was yours, because i thought yours had a standard transmission with a floor shift?

    What have you done to your square lately??

    Here's what I did my square lately. I drove it 900+ miles round trip to C10 Nationals in Nashville with my daughter. We had a great time. I'm pretty sure I saw @TotalyHucked's Truck in front of our hotel in Murfreesboro. I was really damn nervous about driving a pretty much all original 41...

    question about gmc vs chevy

    I remember the day my older cousin (that i always thought of as my uncle) bought a brand new Chevy OBS RCSB, it was about 1989. It had a Chevrolet logo on the driver's door and a GMC logo on the passenger door. Nobody noticed until my dad pointed it out. My cousin took it back to the...
