No a friend of mine builds them, and wholesales them to me, I retail them. I also have 67-72 small block V8 motor mount limiters, and shock plates he makes. The shock plates will fit for any mopar 3" axle tube, but are also slightly slotted to also fit a for 8.8 axle tube for an explorer 8.8 swap.
I make battery cable assemblies for 76-62 Small block V8 A body, and dual 3.5" dash speaker mounts.
