Thanks guys I'm basically planning my rear end..
I want an Ahmed rear beam so have bought the 2wd beam and 4x4 trailing arms to be converted..... 2wd rear beam as I am planning for a 7'5" rear case with an Quaife ATB but I haven't bought the 7'5" diff to be rebuilt yet with the ATB so was wondering whether to buy a 2wd 7'5" or a Granada 7'5 with the 4x4 output flanges..

So in summary I can fit either 2wd shafts or 4x4 shafts depending on which rear diff I buy.. so what are the best ones?
