hi guys thanks for the replys, i used the scorpio floor pan as i had two of the cars lying around at the time.
so the front coilovers will have to be custom made to fit?? i was thinking if i got sierra ones and used adjuastable top mounts on the front they would fit. as for diffs etc im happy with the hefty scorpio ones as the diff is viscous and the roll bars are big enough.
as for using the floor pan over the sierra it was a better option i tought due to the extra wide track, more room in the engine bay and the mountings for my 24v v6 where spot on. its also reinforced in places where the sierra was not, the front foot wells like the sierra competiton shells are double skinned etc.
