Hello All, I have a 91 GMC K2500 with 61k that I purchased from the local fire dept at auction. I've recently replaced all the fuel lines and tank and most recently the starter. After replacing the starter I noticed that 1 of the bolts doesn't get too tight which tells me it's stripped out up in the block. I purchased new bolts from the dealer to make sure I got the 10mm that it requires so my question is what do you think is the easiest fix for this? Heli coils and some thread lock red? Thank you
