Replaced shocks over the w/e. Got to the back. Bottoms came off great. Rear driver's was tough. Rear pass. was very very hard. Long story short, got the rear driver top off but could get the rear pass off...the bolt just spins. After looking at the rear driver top, I notice the threads were in very bad shape i.e. the bolt will now not thread on. So, 1) Should I just weld in some new supports or re thread with a die? Still have to get the rear pass off so welding certainly would be easier (I think). Also, is there any options on the type of bolt to use on the shock mounts. I do not really like the pin/bolt combo. Has any mounted with Plastic lock nuts? Euro cars do this. Seems like it would work since there is little horizontal force applied to the shocks. Thanks.
