1973 Swinger, 318 a/c car. I did the PST 1.03” bars couple years back and highly recommend them. I still have comfortable ride but partnered with all the other updgrades/improvements, it handles in no way like it was ever intended to now. I daily it when weather allows and have done several lengthy trips with it and it’s great. I chose to loosen the adjusters for lowered ride height while still maintaining spring rate. Hope this helps.
