Hello Buickfriend.Tanks for pics.I Put my lady 54 in garage,under jacs over winterStubbe, where have you been? Have not heard from you in a while. My car is a 1952 Buick but I think it is real similar. The original shocks also leaked and did not control things. I put telescoping shocks on it. I chose shocks that where from a half ton Chevrolet pickup. I copied their mounting design for angles. They work very well. On my car there is a cross member just above the rear axle and a little behind it. I fabricated shock mounts and welded them to the cross member. The pan hard bar is in the same area so you have to work around it. I fabricated lower mounts and welded them to the rear axle. As I mentioned I used the Chevrolet design. The top of the shocks are mounted near the center of the car and the bottom of the shocks are mounted near the wheels. I did this six or seven years ago and have quit a few thousand miles on them with no problems. Stubbe, I could probably get some pictures and dimensions if you are interested.
