The bracket that goes from the tranfercase to the bell housing
I'm missing the bolt that goes into the bell housing...I guess I don't have the bolt in my misc pile...

Any help is greatly appreciated. It's driving me nuts and I have a knock when decelerating...I'm hopin this is it.

1987 GMC high sierra btw..

If the bolt passes through the bellhousing and goes into the rear of the block, it's a 3/8-16.
My 84 K10 has that bracket but I'm too wiped out from today to crawl under and look.
But I seem to recall it sets against the bellhousing and bolts to the block.
