I'm using their rails and they're pretty nice for sure, but not really any diferent from American Stamping aside from they conme C'd at the back. I don't know about using their "channel boxing plates tho - seems like overkill to me( think of the weight!). I got their regular plates with the rails and they're a really good fit and will do just fine over the other ones. This chassis is for a 32 coupe but I think the regular rails and plates would be fine for a fat fendered car too.
