Re: AC Compressor hoses connector bolt
Just did one on my 73 GMC. Replaced factory A6 compressor with a Pro6Ten. Your bolt is only long enough to hold the seal plate on and you will have to add for the line block. The AC bolt I just bought for mine was a 10mm x 1.50mm x 45mm long. That's using a washer head metric bolt if you are using a no flange metric bolt take into consideration for a washer or lock washer thickness. I use my digital caliper to measure the thread hole depth and round it down to the next shorter bolt length(generally 5mm increments) to get maximum threads in that aluminum bore. Also note all your mounting bolts will be metric also in case your original need updated.
