Could the HAMB world assist with how the rear hubs assemble on a 1940 Ford banjo rear end? As I disassembled a pair of rear hubs there was the roller bearing, followed by the seal, then by a snap ring. However there are two snap ring grooves in the hub. I'd have to believe there should be a dedicated snap ring or thrush washer holding the roller bearing in place, and there appears to be a groove for one, is that not correct? Also, can anyone provide me with the dimensions for the emergency brake horizontal bar? The pin holes are all oblong and I'm not sure where they should be located after welding up the holes. Thanks in advance!
