I was reading articles about building up a gm 10 bolt diff.

They all said to put in a solid pinion spacer.

I phoned and ordered one from Drive Train Direct. I had to call back the next day b/c they had to put together a shipping quote for me to Canada.

That was almost a month ago.

I have called back about 4 times and they keep telling me that their shipping dept. screwed up and have not shipped it yet.

I have not got the part yet but at least they have not charged my credit card yet!!
