    Please Help I'm Stuck!

    No - wire harnesses were specific to the option content of the truck. So you might have 20 or 30 wiring harness part numbers to cover the possible one million build combinations. In some cases, or for service parts, you might give away a branch or a connector (taped back) depending on the...

    Does it still have the SPID label in the glovebox? Cruise is RPO K34. K

    Bed mounting hardware for short box step side.

    The bolts themselves are the same as the fleetside box bolts (there weren't unique bolts between the two). Short vs Long usage would vary based on engine type and subsequent exhaust type (LH side, RH side or dual exhaust). The short bolts are the default; the long bolts were to provide easier...

    Questions about JB7 Brakes

    Here's the brake chart for the '79 JB-7 trucks. Unfortunately the hole for the three ring binder goes right through where I want to see. I assume that is the K20 column (column 24). If so, your two choices for GVW are either 6800 or 8400 lb GVW. K

    Have you checked your ground?

    I used to ask questions of the electrical Vehicle System Engineer all the time. I had him on speed dial from the back barn to his pager. "Hey Jerry" I'd say. "I've got this problem - "Bad ground" he'd say. "You didn't even let me finish!" "I know. Start by checking the grounds". Usually...

    Show your daily driver

    I'm a bit remiss but I got a new daily driver back in May of this year. Sold the Duramax to a kid local to me and picked up this 2015 Silverado. Found it in Mississippi during a business trip and drove it back. 5.3L, 6 speed auto, 3.73 gears. Seems to be working out so far. It had never...

    (1980 Chevy Squarebody) CKL14A1101673 In search of my fathers old truck

    No - the Heritage Center would not have owner information (unless the original owner appears on the original invoice). K

    Truck cover

    I don't know if these guys make covers for trucks but I am very happy with the one that came with my camp trailer. It's from classic accessories. It fits nice and tight. This will be its fifth winter and still looks brand new. K

    Best way to run power from truck battery to trailer winch. Quick disconnect ends.

    This is basically what I do. There are two batteries in the race car. On the rare occasion I need to use the winch I take the easy battery out of the car and use that to run the winch. K

    Confusing VIN number for 80 pickup

    Ackshully - it's more of a "serial" portion. The numbers were assigned sequentially, starting at 100001 for Chevy and 500001 for GMC, but they were not built in that order (Chevys with about every ninth vehicle being built as a GMC). Think of it like a checkbook: you write the checks in order...

    Top door hinge to door bolt one smaller than the rest

    Looks to me like the bolt that holds the window track, or maybe the bottom of the vent window. All the other ones are part number 3846202, and provided by either Lang or Ferndale Fasteners (same as the fender nose bolts). ;) K

    81-87 fenders and doors on a 78, will it work without modifications

    Not sure about the window regulators but you will definitely need new bumper, rad support, grill, grille filler panel, headlamps, headlamp bezels, grille trim, hood hinges, hood, cowl, etc, in order to use the fenders. K

    Color Search

    Having said that: I suggest you send your VIN to the Heritage Center and ask for a copy of the original invoice. The invoice will include build timing, original RPO content and pricing, plus any available discounts, and selling dealer information. Then you will know for sure. K

    Intermittent steering wander?

    Agree - best to visit an alignment shop. Without data you are just spitballing. But - the caster shims do come in known amounts, so you would know how much you are adding. K

    Intermittent steering wander?

    What's your caster check at? I would run a ton of caster in that setup - like 10 degrees. Toe needs to be in - like 1/8". Straightening the steering wheel is easy. Just adjust the fore/aft drag link until the wheel is where you want it. It does not affect the front end geometry. K

    New to the forum, but not to Squarebodies...

    Thank you for posting that; that is what is known as a SPID label (Service Parts ID label). The build sheet is what the line workers refer to so they know which parts to put on. They are pretty rare which is why I was excited to potentially see one. K Build sheet:

    New to the forum, but not to Squarebodies...

    So - according to the chart above 3.73 was base; 4.10 and 4.56 were regular available options. Not special (other than being selected from the available offerings) and not beefed up beyond normal K20. K
