Thread size for '48-'52 F1 Leaf Spring U-Bolts

[supereal]

C&G (800) 266-0470 has them for 48-52 pickups, Order B3C-5455-A You will need four. Order nuts, as well. The U-bolts cost $7.95 each It is a very good idea to install new ones. Old ones are usually rusted, making proper tightening uneven. Ford has always used odd thread pitches, so we save all threaded pieces and bolts for future use, if needed.
