Iam getting ready to pull a 5 speed zf out of an 89 f150 4wd to put in a 1987 f250 4wd /crew cab can anyone tell me from some experience if this swap is drama free. will the back part of the tranny hook up with the drive shaft and is the length made up by the length of the drive shafts since this is a longer truck (crew cab) any help in this matter would be appreciated
