Will a 73-77 8.5 10 bolt fit in a 70?

welcome to the forum.
IIRC the upper control arms mount point/position was changed.
i have heard of some special upper control arms to put a 64-72 rear axle into the 73-77 cars though..........

The short answer is no. It will not fit.

Ok ...thank you... Did any 71 or 72 models have a 8.5 or were they all 8.2 up to the wider 73+ housings?

The 10 bolt Chevelle rear end has the 8.2" ring gear from 1964 to 1972. It wasn't until late 1972 that the 10 bolt 8.5" ring gear was used in Chevelles although many aftermarket parts listings show 70-76 for the 8.5" rear end for Chevelles.
