Using the discount codes at RA, along with their great prices is great but there will be a time when you need a part asap and have to do the "hundred dollar to death" walk, whether you like it or not. That is why this thread is great because now you have others helping you prepare for this swap. IMO, the tune parts, all fresh gaskets and seals, mounts, hoses, belts, clamps, filters, fluids, available harnesses and wear items all should be swapped out.
