Used FoMoCo I beam axle. Based on the measurements I believe it to be 37-41. Was told it came of a 1939 Ford Truck. Came with the car I purchased and I'm not going to need it. $200 Also have the 39 front split bones, square back spindles and what I was told is an old Magnum tube drop axle available soon. 8BA flywheel and Bellhousing. Just removed from a 1949 8RT Ford Flathead truck engine. Decided I don't need these parts and don't want to store them until I may want to use them. Complete Bellhousing, pressure plate, starter plate and flywheel. All the original Ford fasteners too. $200 Ford Flathead 8BA cast iron bellhousing. Starter nose cone is beat up. $75 SOLD 1940 Ford Rear Axle and Leaf Spring. $50
