I installed a 4 speed saginaw tranmission in my 1953 Chevy truck. The transmision has a boss at the bottom of the tailshaft that looks like it was used in the original car (Camaro?) for some sort of mount. The way the tranmission mounts to the 235 engine it looks like is pretty well mounted. Do you think I need to install the crossmember 79-505 that Classic Parts sells? Am I ok without it? Do I gain anything if I install this cross member? Thanks, Antonio 1953 3100
