Wilcox makes an adapter that adapts flathead chry. products to chev. bell housing to use any transmission that fits a standard late model chev bolt pattern. The adapter comes with flywheel and uses late chry. starter in either right or left locations. It requires a 10 1/2" Chev. clutch. The price I was quoted was $695.00 complete. You might ask Don Coatney what he estimates it would cost to duplicate his installation if you had to have someone else do the welding and machine work.
