Recovery going well, left knee replaced last Nov., right hip in August. In therapy and walking without a cane. Thanks for the offer, I still can't ride that far in a car. If you drill the head off the bolts, the head will lift off, then you can get on the bolt with a pair of vise grips, a block of wood on the block and a pry bar between the vise grips and wood, a little upward pressure and the bolts should unscrew. Don't know how easy the bolt head will drill though. Could be a bugger. You should be able to sell the head if it is OK. I'll have to wait awhile before I could come up to help but will think about it as an option. Thanks for the offer!
