nothing is the same as a cossie,if its an early gearbox with reverse beside 1st then the bellhousing is useful for a v6 to 2wd type 9 gearbox conversion,the rear diff is worth about £100,the rear beam and arms are the same as any other sierra with an arb.the brakes are smaller too.a guy i know had a nice caspian blue xr4x4 that needed a small amount of welding,he couldnt get £400 for it recently so he sold some parts and weighed the rest in,it was a nice straight xr but nobody wanted it.
