Turbo charged sbc

I bought my 71 Camaro SS a few years ago with a single turbo setup installed on the origional 5.7, but with a rebuild and low compression pistons. The install was done in 1984, making the damn thing as old as I am, and I'm having a hell of a time finding replacement/rebuild parts for this thing. The turbo is non-ball bearing, made by Rayjay, which isn't really the problem since Rayjay is still doing bussiness so I'm sure I can still get parts from them.
The problem is with the 2 stage plenum style turbo intake manifold made by a company called Martin (marked 350-01A). I cannot for the life of me find anything on the internet about this thing, or where to get gaskets and such for it.:banghead: Btw, this is a suck through system, with no "hat" on top of the carb. If any of you older muscle car guys have any insite on this setup, any information would greatly be appreciated. If pictures are needed for more of an idea about what the hell I'm talking about, I can have some within a couple of days.

Not sure what a martin looks like, what about this one on ebay item # 7956231434 Hope this helps.

I would jump on http://www.boostedhorsepower.com/Blowthru/Forums/index.php and see if those guys can help you out.
