I think Spax may still list shocks for them.
As for springs...very hit and miss. Most just seem to drop them onto the bump stops....which is crap.
When I was using normal type springs, I think I ended up with Pi fronts, and Spax rears. Eitehr way, it was still too low.
Some models came with a diff, not many though, so very unlikely it has one.
Ex cop cars, 2.8i specials etc are likely candidates.
No bits of other fords will fit easily.
Also ask here.
