67 pontiac posi

this is from the 67 bonneville i parted out. it is a 2.73 posi everything looks good inside. $500 complete rearend picked up from area code 44077 or i can remove the carrier and gears and ship them for $400+shipping.

 

this isn't 9 3/8ths by any chance are they? If so would that fit a 72' electra?

 

It will not fit.
