My Bud has the original k frame it his challenger race car .Lucky the control arm break was after he put the car back in the trailer. As it turns out Magnum force did an upgrade due this issue with street cars breaking them more often. Magnum Force will not remake these even in a thicker wall size. We checked with S & W they may make a set but not sure. Any body know of a set hanging on a wall or one of the talented moparts guys who is familiar with this and can make a set. ?? Thanks
