Why under no circumstances Mike, im curious now? i spoke to a few people off here whilst doing my underside resto recently and nobody said not to change them for poly items, and as has been said above one of the sides to the rear arms is discontinued so what choice have you got

Ive just done mine and honestly theyre fine, poly bushed rear ARB but put the standard ford main beam bushes back in as i was told very reliably that they were the best bushes available and that ford spent a lot of time in there development.
