Looks like there was/is a change,
9.3.26. FUEL CELL SPECIFICATIONS
All cars must be equipped with a safety fuel cell complying with these specifications, except for Touring,Spec Miata, Improved Touring, American Sedan restricted prep, production-based Vintage cars, and cars where the stock fuel tank is located between the axle center lines and within the main chassis structure (i.e.,frame rails, etc.).
The added language describes the SR1 (and most Radicals) as they left the factory.
so now it looks like I should be able to run with the local SCCA here.
So the new language says that metal tanks in Radicals is acceptable....that’s great news!
That's the way I read it, but someone pointed out that the P1 & P2 rules sections require a fuel cell. But I didn't see the same requirement in ASR.
