crossmember

I have a 1970 98 with the 455 and single exhaust. I have access to a '68 dual hump crossmember from a 98. Will that fit my 1970 so I can install duals? I know I need a different drivers side exhaust manifold for that and know where to get that also, but if anyone knows if this swap would work, it would be very helpful. Thanks,

Welcome to AF. Not positive, but lay it up in there and see if fits, one easy way, no?

Thank you Max for the reply. I assumed it had a single hump crossmember as I just got the car and am not familiar with those big land yachts and it had only one tube sticking out the back. But when I went under it today after work, it came with a dual hump already. Gotta love the way they set them up back then.
