Spare seat? Seat measurements?

[jjvd21]

Does anyone have a spare D3 seat? I'm trying to determine the measurement between the bolts that hold the seat base to the seat rails (track). Any insight would be appreciated. Thanks!

I'm looking to do the Nwoods seat mod that gives extra leg room and the measurements are necessary for the fabricator. Anyone? Thanks!!!!!
