The 1992 RB-1 is very nice with Roly Poly tires. I would guess that in 1992 and 1993, the clearance did not get tighter.
I know the '91 and '90 would be similar to the '92. I can't speak to years prior, because the geometry of RB-1's was changed after '89, and the RB-1 we usually talk about had the geometry of 1990 through 1994. If you don't know the year, do you have any color details of the one you're getting?
