Any tips for getting the drain plug loose on my 85 K20 rear diff? Searched and have tried heat, PB blaster, etc.....this thing is not budging....I'm using a 3/8" ratchet extension and it's not the snuggest fit....afraid of stripping...any ideas? Thought about welding a short grade 8 bolt to it...Thanks, Happy Friday Everyone

In another thread it was suggested to use an impact to jolt it loose. Never had to pull one, but it's worth a try before you start welding.

I feel like I've joined an exclusive club where the members are only those that have removed a rusty bugger of a pinion nut on the rear differential...WOW..that was about the most difficult thing I've ever messed with on this 25 plus year old truck. There should at least be a prize or something lol btw- Tried two buddies impact wrenches with no success, heat, PB Blaster....in the end a 4 ft breaker bar on a 1.25" impact socket saved the day...er night. Time for a cold beer..
