I am getting ready to install a 4 speed into a Riv. I have been looking at T-10 trans because they are cheaper than the Muncies. Any strong trans that has the same output as a Turbo 400 to make the switch a little easier. I would like a low first gear since it is a big car. I need a flywheel, A body pedals with all parts, Bell housing and shifter. I will take any, or all-in-one. Thanks, John
