What holds the pins in the seat housing? What is the best way to remove the pins to replace the bushings?

If I remember right there is roll pins holding the rods in the seat. Go to town and buy a roll pin punch to fit the size pin you have, then the rod should drive right out. I think there is one rod that has a pair of keepers on them, just pry off with pliers for that one.

They are held in with a teeny weeny roll pin that is very difficult to get out after 40 years. I always lay the seat frame on its side and with a 4 lb hammer and a correct size punch just drive the pins sideways shearing off the roll pins. Sometimes I never use the roll pins on reassembly and just tack weld the pivot pins on each end.

Ditto on the roll pins, if your lucky you can drive them out, but boy are they small you wanna have more than one roll pin punch. I use stainless steel rod when going back together, what ever you do dont put roll pins back in, either tack weld or drill a hole thru the pin where the roll pin was and use a small cotter key.

I followed the pounding out the roll pin advice and it was very easy. When I had the pins out, alot of them were wore along with the bushings. So I got a piece of rod stock and cut new ones to length. Then I drilled new holes where the pins were and just placed cotter keys in there so there were easier to remove if the seat bushings wear out again in 50 years!!
