    Idle screw caps?

    The factory suggested method looks like such a hack when they are broken out.

    Old Delco 2700 "ETR"

    I can do this stuff, but seem to lack the motivation to get it set up on the bench (lacking space, coffee table and dining table set ups). If I use the 'new' one, I may have to add the aux input. I've added them to all our cars

    Old Delco 2700 "ETR"

    I think this is the same family, I had never found one that was fully functional until today. It is a 1982 with a repair tag from 1987. I can cut the long, plastic mounting ears to use in my truck (AFAIK, if I decide the swap out the newer analog Delco). I should have taken a picture of it in...

    White strap under gauge cluster on 74

    I don't recognize it, but it sure appears to be a fiber optic light source for the wiper switch. The end you are holding would plug into the light source. Here is a much later style GM unit. The end is sticking up in front of the vent.

    88 Caprice Classic Wagon

    I learned something new. I thought sure they stayed that way until the body change. Early 307s even had belt driven vacuum pumps to run accessories and brakes, so I'm really surprised.

    88 Caprice Classic Wagon

    Wagons all have Hydroboost brakes too.

    88 Caprice Classic Wagon

    They are plenty durable in this late form, the 307 even has a roller cam, just rather anemic. GM even claimed the wagons had a 5000lb tow rating when properly equipped, IIRC. I've never heard an official reason, but I can only assume that this anomaly was justified to keep the Olds V8 in...

    88 Caprice Classic Wagon

    They make 305s look better.

    88 Caprice Classic Wagon

    It should be a 200R4. No BOP bolt pattern 700R4. When the B wagons went to the Olds 307 in early '86, no more Chevy powered wagons or 700s until the new body.

    Loud Bang, something broke, then bad vibration in park or driving

    We had a Big 10 do that when it was fairly new at my family's business. Left a big dent upward in the hood!

    Seeking 7.5” 10 Bolt Advice...

    7.5 axles are all 4.75 pattern while 8.5s were available in both, IIRC.

    Is that a Delco or an Audiovox? unit?

    85 C20 LWB eight lug bolt pattern compatible late model chevy

    No fitment issues on my 2WD at all. My C20 does have HD brakes. I've got tires on it now (LT225 75 R16, IIRC) that are within 1% of the original 8.75/16.5 tires.

    Mystery valve... came out 78 400 th350

    Makes sense, the EGTs from that setup could be staggering.

    Someone has that monstrosity for sale on our local CL. I imagine the manifolds ran shockingly hot.

    Harbor Freight Recalls REPLACEMENT Jack Stands

    I have some old, orange, 3 ton Allied ones as well. I don't think I got them from HF.

    Mystery valve... came out 78 400 th350

    Computer Control Command is the GM name for the electronic feedback fuel system starting (U.S. Federal emissions) with cars in 1981 (similar for Cali in 1980). Heavy Duty emissions is kind of a misnomer. They were easier to meet standards, for higher GVW trucks that were phased in over the...

    Mystery valve... came out 78 400 th350

    That's from a CCC system, or from a truck with HD emissions with the little controller box on the firewall (possibly).

    AC HELP NEEDED..

    Here is the sadistic GM sealing washer chart. I had to fix a leaking O-ring (the swtich port) on my R4 this year. Surprisingly, NAPA had a listing for that particular O-ring and the yellow and green (IIRC) sealing washers I needed. Additionally, an old A6 compressor would have value to some...

    Yep, shockingly easy.

    another elco

    If you still have a good A6 compressor, I can't say enough good about the double lip shaft seal that can be installed in place of the ceramic shaft seal and 'bird cage' assembly (as well as later single lip seals). It's funny that GM finally came out with a great front seal that fits compressors...

    85 C20 LWB eight lug bolt pattern compatible late model chevy

    I had to go to the Boise and Nampa stores both to get 32 of them. I was shocked they had the SAE threads for the studs and the external thread that fit the matching center caps. The had them readily in the lug nut bins they sell for replacements. This was back in 2009. They are a 7/8 inch hex...

    85 C20 LWB eight lug bolt pattern compatible late model chevy

    That's my C20 in the background with 2002 3/4 ton aluminum wheels. Got the lug nuts from Costco (of all places).

    This genuinely offends me

    Might need a tetanus shot after a test drive.
