Trying to plan for my swap since it's my daily driver. I'm swapping an Olds 350/th350 from a 76 Cutlass into an 80 LeMans that originally had a 229 Chevy with the th200 trans and a 7.5 rear. The rear and driveshaft are still sitting in the car. Will the Olds th350 trans fit in that with that combo? Thanks.
