From the RPM ULTRA MOLD BUGGY first page. There was a little confusion in to why RPM put 91 WORLDS on this conversion, as back at the WORLDS in Detroit the STEALTH car was run.
Well after some research on this, it turns out both were used at the 91 WORLDS in Detroit.
The Team Drivers who did not run the STEALTH car ran the RPM Conversions.
They turned up at the track with RPM front ends made up and were bolted to the RC10 Team Cars and run at the 91 WORLDS. They were also said to have run with 15 degree castor blocks and the RC10T Bell-cranks.......
So there you have it. It was called the 91 WORLDS KIT because it was used at the 91 WORLDS............
