I have a 49' 3100 which needs a new drivetrain. I want to keep a 235 motor in it, but replace the trans with a 350. I need a little help with the mounts. I want to keep the front mount for the motor. I would also like to keep the existing mount that the bell housing sits on. So, do I need another mount for the 350 trans? Or do I have to remove the existing mount and replace it with one that fits a 350? Also, does anyone have a good source for rebuilt 235 motor's. I might rebuild mine, but if the price it right, I would go for one I could drop in.
