Re: "Papa Smurf" - 1966 GMC 1500 Custom
New alternator is installed, HEI distributor fits, and my electric oil pressure sensor just barely fits. Tomorrow I plan on actually wiring these all up. I also installed new spark plugs gapped at .045 for the new HEI distributor. I'll be replacing spark plugs wires as well.
When I pulled my wiring harness today I saw the horrors of 50+ years of custom wiring. The harness is a complete mess. After trimming most of the terminated wires I think I can finally makes sense of what the harness was meant to do.
Once I get everything back together I'll let you all know about part numbers and wiring diagrams.
On an interesting note, whoever installed the last distributor forgot the gasket. So I solved one major oil leak there. They also did not use any sort of sealant on the mechanical oil gauge, so that is a second leak solved (assuming I used enough of the proper sealant). At least I know for certain this gauge won't leak inside the cab. Lol.
