LT1 T56 Transmission to LA 360 swap

Yeah, I should have clarified but that’s why I mentioned if first gear was the same because if they are you can mix and match the input to get the desired length so an LS1 input in an LT1 trans (so long as it’s not the two early ones with different gearsets)
the cobra input is short, the lt1 input is short too but longer than the cobra, the ls is longer yet and the viper is longer yet.
I’ve never seen an Aston Martin trans so I can’t speak to that and I’m hoping for measurements from the Dodge Challenger tr6060 soon

I’m converting my c6 vette t56 to work in my 99 f150, had I not had a cobra midplate id be using an lt1 midplate.

I’m converting a camaro tr6060 to be used in my 71 cutlass behind an Oldsmobile.
