I have an older V-Rex with a 1.5 inch top tube covered with the 3-sided aluminum bracket. It has the old style skewer seat post attachment. I wanted to change to the M5 seat (or something similar) and I talked to Rans about it. They suggested that others have retrofitted the M5 seat to older V-Rexs and that maybe there was information out there dealing with this conversion. Has anyone done this? Is it difficult? Could I put the old seatpost attachment on the M5?

Any help is greatly appreciated.
