I would like to adjust my stance. Making the rear higher. I’m thinking an adjustable strut could replace the tube shocks and get the look I’m seeking.
If you have a good set of original shocks they do quite well. As for adding tube shocks, there are brackets that show up on ebay quite often for the rear of 35-40 cars and trucks.
Perhaps I.m missing something as I am not clear as to what you really want to do and what type of suspension you already have under the car.
