Martin's design is still in his head. That is why I went with products currently in production. Faulting an owner for buying products already available rather than waiting for you to produce something at some untold date in the future is ludicrous. Ed's brackets may not be perfect, but at least they are here. Same with Byrne's LCA's, which are the only LCA's now available BTW (Houston no longer sells Bryan's). Crappy folded up rust and stress crack prone sheet metal OEM arms have of course been NLA for years. (Is it just me, or does making suspension components out of the same metal typically reserved for fenders and door skins strike anyone else as a bad idea?)

To be brutally honest, Byrne did more pre-release engineering than Bryan Pearce did on his arms. The design has been in use for more than a decade with no reported problems, so it is certainly service tested (far more extensively than the cheap folded up 16 gauge LCA's original to the car). > > Don't know how Ed handled bracket engineering. Since they are sold by DMC franchises I have to assume they have Houston's blessing.
