i have a 68 b'cuda with a 440- and VICTOR HEADS
I can only tell you what did not fit my car.
I am running a andy f- front motor plate, but i mounted it before i took off my stock motor mounts, so i believe i am in stock location.
CPPA's did not fit- i would have had to make my steering column go right through the middle of my #7 exhaust pipe. they laid all over the inner fender, touching the whole way.
Proparts- did not fit, hit just about everything and then would not make it under the chassis about 1/8" to high to clear the bottom of the car.
headman- fendewell headers do not fit. they sit on the shock tower on the passenger side, and i mean SIT looking to "modify" a 1/4" deep on the #2 cylinder to allow them to work.
what worked on my car- the set i am building!!!!
