[QUOTE=dojj;4538882]if it's an xr4x4 shell then it's going to have 5 doors

but is it a pre 87 shell? 87-89 shell

Hi mate an old post but had quick question. I have been offered a 1986 Sierra 5 door shell xr4x4. It's a mint shell now I have s rotten saph cosworth. Is the running gear mounting points all the same? I.e could I transfer all my cosworth running gear to a xr4x4 shell?
