i have a lift for an older year ranger and wondered if ford ever changed the thread size on the trucks? i was gonna use the lift blocks and pucks on a trailer project. i was just gonna use a set of speed nuts from the frame and just wondered if any year truck would work when i visited the pic and pull?? ( this is for my atv to use at the fire hall as a recovery trailer during hunting season/ emergency's in BFE) TKS IN ADVANCE FOR ANY IDEAS YOU HAVE PLEASE SHARE.
