'72 Firewall Help
Guys I can't remember all the Firewall holes on the Drivers side of my '72 Blazer. See the picture with my notes on it. What are the 2 holes circled in red.
The lower is 0.75" diameter. I didn't measure the upper one but it is probably around 1.25" diameter.
I think the smaller one may be Tach ??
Maybe these aren't both factory ??
Unfortunately I don't have a good picture of this area of my truck before I tore it all apart.
Thanks for any help.
