No I haven`t seen that many Novas of your years Pro-toured.And I have seen only one with a big block in it.But there are suspension pieces for those cars. Even though the suspension set up is a little strange.The front end is second Gen Camaro/Firebird.And the rear end is 1968 -74 Nova.and usually has a 8,5 10 bolt rear end .Like a 1973-4 Nova.So all those suspension pieces should fit.
