These are the springs, I'm not going into marketing and not looking to make a profit, I have asked for a price from the spring man and he wants $125 per set or he will do 10 sets for $75 per set, but if nobody needs them then I will proceed with the one set. They will probably be a slightly thicker gauge but as you can see they are counter wound and have a shorter end connection onto the seat, similar to a bantam but not as long.
