I have a 520H, 416-8, Charger 12, and a Raider 12. I would like to put oem replacement seats on them. They all have out lived their original seats and have Tractor Supply replacements on them which are ok just not original. I am getting ready to do a full resto on the Raider and would really like to put an original style seat on it. I plan to do a like new resto on it.
