Lynn,
   Probabl= y I have not looked deep enough but the only solid corner seals I found at "Mazdatrix"
were for early 12A/1= 3B engines with 3mm apex seals..........

Well, thank you for that.
 
Let me make a subject more clear.
 There are sources for after market 4130 steel corner seals. Typi= cally used in boosted drag racing engines. I have no data on such equipment= , and have never failed the early Mazda solid corner seals. So the steel se= als were of no interest to me. The stock solid seals are strong enough to r= ace on in a normally aspirated engine.
And even those are powdered metal. Mazda makes really good pieces. All= other engine parts must be proven superior to Mazda parts before I would u= se them.
 
The Racing Beat catalogue/manual is a free download from their site. F= ull of solid data and suggestions from people who have incinerated more dyn= o engines than you or they  could count. They know more about rotaries= than anyone, and its free.
 
Rotor bearings that show off shiny spots should be discarded. You can = buy oversized bearings to get more clearance which is good. If you have a h= int of copper showing and shiny spots the overlay (the gray stuff) has move= d under high heat. The bearing now has too little clearance in the shiny sp= ots and a bit too much in the copper spots. Throw that bearing away. Press = in new bearings. Grind off the indexing tab first. No index to any holes is= needed in the rotors. Mazda used to install 3 set screws that engaged the = bearing and the rotor. This made a lost bearing into a massive failure with= a sudden stoppage when the screws acted like a roller clamping system when= the bearing tried to rotate in the rotor during a lubrication failure. No = such screws have been used in years.
For main bearings the indexing tab must be maintained to be sure lubri= cation holes in the bearing shell align with holes in the stationary gear. =
