I used to have an 89F Plate RRC with loads of goodies - now gone to the scrapyard in the sky.
I kept all the good bits though. So far I have transferred +2" springs, +2" shocks, +2" spring spacers, SR tubular turrets, SR rear shock mounts, SR caster corrected radius arms (just finished those today), diff guards, steering bash plate, +2" SR bump stops and all polybushes to my 95N Disco.
Still to fit, SR rear trailing arms, SR double carden prop, SR wide angle prop.
The reason I bought the Disco is that I knew all bits would be transferable.
Good luck.
:P
