every viper transplant into a 60s era muscle car i've ever seen has had to chop the firewall. My Charger had a whole 2 inches from the firewall to the back of the block, no way your getting another 2 pistons in there and the front of the block didn't have any extra room to the radiator either.
i have followed along with a 6 spd transplant into another 70 RR and the whole trans tunnel had to be widened and squared up on top to fit the T56.
Yes, the trans had 2 different places to mount the shifter but maybe Tim didn't know that at the time or didn't have the money to buy the extra pieces to move it (maybe it doesn't take any extra pieces, i don't know) or maybe he said, "this is mine and this is the way i want to do it".
Its short sighted, closed minded people like you that stifle creativity and turn this world to shit by putting down everything you see unless you created it, oh wait, you haven't created shit have you?? I was excluded from the local Mopar club simply because i wanted to make my Charger different from all the other ones out there, thats part of the reason i never got back to it, i kept wondering if maybe i was doing something wrong since the "crowd" didn't like it. but i should have, i should have finished it and shoved the damn thing down their throat at every show they went to.
oh by the way, heres just a couple of cars that got chopped, sometimes by well respected professional shops, sorry, maybe i should have said CHOP SHOP
