I am starting to work on my 1930 Ford 2 Dr Sedan. I am planing to use either 17" or 16" Ford wire wheels on it (I have a set of each). I have a 1937 Ford front axle and bones to use up front. Out back I am going to use a 9" from an '86 Ford pickup truck. This axle is allot wider than I need. I would like to know what the outside of hub to outside of hub length is on both the 30 and 37 rear axle so I can appropriately narrow my old 9". Thanks! Mike
Best solution is the set the Model A on jack stands and then put the tires/rims you want to use in the position you want them and then measure the distance ( wheel mounting flange to wheel mounting flange ) . Then you would know for sure ... BUT ... Most Model A guys running fenders want a rear end that is 56 inches wide ( WMS to WMS ). A 5 lug Maverick rear end is that exact width ...
just happen to have a 37 rear end sitting in my garage the measurement is 51.5 that is inside backing plate to plate
