I got one of Scott Mock's prototype rear suspensions. This is the same suspension that is under Kevin Miller's 69 Camaro that has been 2/10ths behind Brian Finch at two Good Guys events. Reasonably and priced and very well made.
Included are the following. Upper shock mount, lower shock mount brackets that attach to the bars, panhard bar w/ end links, panhard bar upper frame mount w/ tube gusset and 2 lower bars with johnny joints. The pictures below don't show the u-bolts and spring pad mounts that are included.
