As title, my car has been off the road for a long time and has had a full engine rebuild, i'm basically at the stage where it's almost ready for an MOT, but i think it will fail on these, so i think it's a good idea to replace them.
Anyway, having never done this before i kinda need a step by step guide on what to do and buy, it's a 4x4 saph if that makes any difference?
Cheers,

Rog.
