can i replace the cab on a 1989 ranger

Ya u can unfortunately there is alot of work before this is able to be done. To start take everything out of the engine compartment including the engine. Then disconect everything fom in the cab like brakes cables etc. Then remove the retention bolts holding the cab to the frame then u just remove and replace with another 1 then the long process of putting stuff back in and replacing what was burnt. Hope this helps best of luck
