The Novak rebuilt SM420 is in and working great! Bolted right up to the bell housing on our 235 1957 engine. The only real change was to move the exhaust pipe over a bit and a new driveline with a new slip yoke was needed. The driveline was done by Driveline shop in Sacramento. The old driveline for the BW R-10 was too short. The shifter cane is located perfectly with plenty of room and is at the correct height. At 2500 rpm we are a bit over 55 mph that's plenty for a truck with drum brakes. Stomp starter fit right in no modifications. The area once occupied by the old tranny is clean without all the monkey motion rods that the PO had attached to a floor converter shifter. So it's been a good choice for me and maybe somebody else out there. Thanks to Bill and Bartamos for their X-tra help! Steve
