318 /340 valve cover

If dash is out thoroughly check it over. You can use a 6v lantern battery for power. Waayyy easier to check/fix while its out on a bench.
Lol, I wish I knew how to do body work. Have fun!
So gauges should be safe and just plug it back in the way it was. Good to know. Looking forward to working on the inside of car, hate body work.
