Has anyone upgraded the old seat with the frame of the new suspension seat without buying the whole seat. Best I remember Deere wanted like 700 bucks for the new seat with the black stripes. I could care less about the black stripes but the new suspension is way better than the old. I have one mower with the old and one with the new suspension seat. I would like to upgrade the suspension frame on the old to match the new. If anyone has done this it would be nice to know the part number and where they bought it and what if cost.
