1974 K5 TH350 Pan Bolts

[Chief Brody]

Does anybody have the specs on the pan bolts....I don't want to have remove one of mine and cause a pan leak....

I need the size and thread so I know what thread chaser to buy.

Save yourself the extra trip to the parts store and get a heli-coil kit to begin with. A thread chaser MAY work just fine if you start from the topside of the threads, but you can not get to the topside of the all the threads. Just drill/tap em out and put the thread repair inserts in, you won't regret it later

Edit: And if you're good, you can:drill/tap/install repair coils...All without removing the pan
