yes, getting rid of the OEM garbage design. had some MP circle track springs, advertised as the OEM spring for the A43 cars. but they are 2 inches too short in the front segment. probably going to order a couple B body XHD springs
I got my five leaf packs from John R Spring many moons ago. Be sure to match the front spring bushings to your caltracs. I ordered the wrong solid bushings when I ordered mine and had to buy them again.
This whole extended spring hangers is not new, just the people who make them are. I think mopar offered 3 versions.
Here are two of the mopar types. Overall length I recall is like just under 7 3/4 of the ones I use on the 414 springs. But id have to measure to be really sure. Visually they are easy to tell apart.
081 no longer exist. thats why i bought the ones fro mancini. also confusing, states 2" longer, but it needs to be 4 inches longer to use SS springs. FMJ are 24 inch fronts.
looks like you had P4122279, no longer exist either
