DO i PUT THIS MEMBER ON BLAST OR NOT???????????????????

I've seen lots of manual trans cases with one or more ears welded back on. Owners change a clutch and dont tighten the ears evenly.:(
Anyway... To weld the ears back on you first have to have the pieces.
If I was promised a good usable case I would probably withhold a portion of the money until we could both settle the score.
290 bucks is a good incentive to find the guy a case. I can imagine the guy had another 300 in a different pocket. He likely has an idea what a trans case and gut transplant will cost too.
Your not seeing and reporting the missing bolt ears in advance is just one of the downfalls that result from haste.
If there is a lesson for all to learn here, Dont allow buyers or sellers push you.
