Thanks again for the reply, but I'm 100% certain that the elastomers from the Manitou 1 and Manitou 2 forks are entirely incompatible and cannot be swapped around - therefore, I'm going to have to source genuine Manitou 1 elastomers only - nothing else will fit or work.
What's most annoying, is that these forks (Manitou 1) had a lifetime warranty on the elastomers, bushings and seals etc - however, the Hays Cycle group that currently own the Answer and Manitou brands are refusing to honour it!
