The 90 and 92 boats are the same, other than maybe the engine air intake shape. What is more important is which hull do you want, T-2 that was first raced in 1987 or T-3 from 1989. The hulls were slightly different but I don't know exactly what those differences are.
Was just doing some checking and found the hull has a 17" picklefork depth. That makes it a bit deep for the 8701 and a bit shallow for the 8901 but still legal for both
I drove a 1992 Budweiser 1/8th scale last weekend. Its a very pretty boat especially in the sun. I can get you some pictures of the model & maybe the paint codes next week if you like.
The boat I drove was a T3 just like the picture you posted. It belongs to Mike Board and is currently in a crate on the way home from Seattle.
