Who has replaced a rear servo??

A section of PVC pipe helps with that. :D
You will need to remove the strut to get the lever far enough back so you can get it out and the new one in. (getting the strut back in place is probably the hardest part) but not too bad.
No valvebody drop needed.

Thanks !! how do you use the PVC ?? 2" or so and use a c clamp To compress the spring?
