Thank-you Mark for the info.

Having learned this, GLR, I have a set from a 72 Coronet in my shed. If you are interested. I have no idea what they are worth. They have been in the "open" position (with springs installed) for a many years since I parted that car in 1997! My cars are 73/74 and I already have a spare set (not for sale). I'm not on here 24/7 but you are welcome to PM or email me.
