My son in law has a 1970 nova and we are wondering if a original ford 9 inch from a 67/70 Mustang would fit and we do not want to tub it thanks for the help

 

67-70 Mustang rearend drum to drum width is 59-1/4". 68-79 Nova rearend is 60-1/4". That makes the Ford rearend 1/2" narrower on each side. It will fit with his current wheels providing they now have more than 1/2" of clearance on the back side. Leaf spring mount placement, and whether they need to be moved, is something you can determine with a tape measure.

 

I should have said wheels like what he has (same backspacing) not the very ones he has, because the Mustang wheel bolt pattern is 4.5" vs the Chevy 4.75".

 

Thanks we just left iola wis swapmeet they had some there for 300 bucks we didn't buy. It where not sure but now we no for the next time we see one thanks again

do they sell some kind of adapter kit For chevy Rims

 

One other option for a very strong rear end for CHEAP is the ford exploder. It is a 8.8 with 31 spline axels and are all over in the yards. Early ones come with the drum brakes and the later ones with disk. Most have posi. and good gears, look up the gear ratio and locker if it has one on the door plate. They are also the 59 something for back spacing and leaf spring perches. Also a 4 1/2 bolt pattern but that can be changed to the GM 4 3/4 pattern if needed.

 

Thanks

 

If going with a Ford Exploder rearend, know that the pinion yoke is offset to the passenger side by almost 4". With all things being parallel, this won't cause vibrations, but keep it in mind for checking driveshaft tunnel clearances in the back.

 

We will try and find one from a car about the same year

 

Take the axles and get them re-drilled to a Chevy bolt pattern.
