Fastback seat

My winter project is to get together all the body parts to convert my roadster into a '72 spec fastback. I have the tank, tail piece and the correct rear fender. The next hurdle is finding a decent seat. So far the RK Leighton reproduction looks the best to me. I got an e-mail back from them the price is 96 pounds plus 91 pounds to ship it to California...ouch. They suggested an alternative buying the seat foam and cover for much less shipping cost and unit price. Does anyone out there have an original seat base they want to sell?

The late Fastback/Interpol side covers, number plate and tail piece bracket are available at Les Emery's Norvil Motorcycles.

Hi David,
Here's an option:
Walridge up here in Canada lists the Leighton fastback seat for $240.55 USD ($305.50 CDN).
Cheers,
Derek
