LHP... if you are interested I had an adapter made to bolt a TH350, 400 etc with standard Chevrolet belhousing pattern to the 4200. Also had a crankshaft adapter made to bolt a flex plate or flywheel for above transmissions. I had originally intended to use a TH200 4-R behind the 4200 I'm putting in my '55 chevy truck, since I had it from a previous project. Ended up going with a 5-speed out of a Colorado since I prefer manual transmissions anyways. Now I'm stuck with a $2500 custom aluminum adapter, anyone interested? -Chuck
