What color combo is your L78 Nova?
I am curious as to what the Suffix code on your 4:10 rearend is?
I know the 70 Deuce Could get a Special 4:10 posi,so would that be the same suffix code the 1970 RPO L78 Nova shared too?
In the 1970 Chevrolet parts books,they do not show any 4:10 Posi suffix code for the 1970 Nova,but they do for the 1969 Nova of a BV 4:10 posi code.Could that have been used in 1970 Nova too?
