Longrange Fastback Seats

Any one know if the LRFastback seat would fit with an Interstate tank, I want to build up an 850 Interback out of the parts I have remaining. As I don't have the seat or tail section I didn't really want to buy a new seat and have to hack into it, second hand doesn't seem to come around to often.

Yes the long range fastback seat fits with an Interstate tank. RK Leighton in England manufactures new long range seats..very good quality.
