Just finished some front end work on the wife's 95 B4U Caprice LT1. I replaced the lower ball joints and cut one coil off the front springs. FYI the Heavy Duty Moog ball joints(K6141) don't fit, or maybe just don't fit the 94-95 Caprices. It may work on 9C1s and Impalas after 1995, I don't know. I am just posting this hoping to save someone out there some time and aggrevation if they are planning to use the HD ball joint because they are a larger diameter and will not fit in the stock A frame. I ended up going with the Moog 6145 ball joints.
