Just curios, My bronco has been lift 5.5 inch and my rear drive shaft is too short. The splines mesh about a half an inch when it is sitting on flat ground. my quetion is, will a later bronco drive shaft work? I know some have the flat bolt face on some of the later models, but some have (I think) a fixed yoke like the EB does. Also will a newer fuel injection maniflod, etc...(like off a late 80's mustang) fit on older carbourated heads? if some one could help me out I would Greatly appreciate it.
