1970's John Deere 100 lawn tractor parts (seat, deck)

I have a 1976 John Deere 100 lawn tractor that I need a few parts for. I need a complete seat in good condition preferably with no rips or tears. It has 4 bolt holes which are 8-1/8" center to center and approximately 3.25" center to center. Also am needing some parts for the deck. It has a 32" deck. I need a spindle assembly and the springs off the deck. If you are parting out one of these mowers, I may end up needing some other parts also since I am in the process of restoring one right.
