I will post pics later, but I got the deluxe seat frame and cushions from TM (Valentine's present from my wife) installed on Ol Ugly the Super A today. The seat frame originally came off my grandfather's Super A, he installed it in 1961, but when I restored it I wanted to make it as "factory" as possible.
I mounted the seat in the same set of holes as it was originally on the Super A. It's adjustable, so after mounting I slid it back as far as it would go. It looks like I can re-mount it back as many as three more holes if I choose. However, I am wondering if it won't be in the way of the rear rockshaft arms then.
So, 100-140 owners (or Super A if you have a deluxe seat), can you show me how you have your seat mounted? It is pretty comfy now but if I could slide it back another hole or two, it would create a little more room for my long legs and, shall we say, "ample" frame....
