One additional Note John, the shop did the work on both seats for $130. I had a board cut for the new base of the Powell D seat and took them the old seat so they could copy the way the original Powell seat had folded material similar to the way a package is wrapped. The shop made the D seat up from scratch, new and very firm foam and new vinyl. It looks perfect. They also cut down the P7 seat, and scanned the logo into there computer for the Super Powell seat and monogramed it all for $130. Sounded pretty good to me.
