Basically, the diff on my sapphire is on its way out and i had a Granada Cosworth that i broke up but ive still got the complete rear suspension set up. My idea was to blast and powder coat the granny beam and arms, rebuild the diff which physically measures 9" (does this mean that the granny has a 9" diff or is it just a coincidence that the casing is that size?) and then swop the whole lot with over at weekend. What do you reckon ?
