Anybody with history on these? http://cgi.ebay.com/ebaymotors/NOS-u-joint-u-bolts-64-72-Buick-Olds-442-GS-skylark-/260648202399
They should fit ALL BOP rears and even full size BOP rears. BUY chevy also has u-bolts and are NOT as wide and fit the 1310 u-joint with 1 1/16" cup The ones that the EBAY guy is suppose to be selling are for the 1 1/8" cup... IF you get these and you have to work on trying to get them to slide into the holes...You have the WRONG ones. Good luck
