'69 Barracuda T56 swap, floor, cross member

DionR said

So they were able to get the trans bolted up without removing any of the floor at the firewall? I understand they had to remove some later to match the new crossmember, but I would have though they would have had to cut a bunch out before even getting it bolted up.

That is what ToddRon says in their instructions. But 72bluNblu, goldduster318, and two other members I have seen had to make their tunnels bigger to get adequate clearance. I haven't seen anyone get away with the min floor cuts like ToddRon shows, maybe someone has, but I haven't seen it, and its not likely I will get away with the min floor cuts either.

Keep in mind vintage mopar k-frames were very sloppy and body tolerances are fairly large on these old cars too. So maybe ToddRon got lucky and didn't need to cut as much floor out. Its gonna vary car to car. Only way to really know is fit it up in there and see.

I did minimum cutting on my replacement floor trans tunnel just to get the floor done because it was a can of worms repairing rust etc needed to get that part done done. Actual required additional cutting welding slicing etc I will be finding out once trans gets raise up, or won't raise up cause it hits the tunnel lol.....
