There was a class called Rear Engine Nostalgia Top Fuel. It was only ran at Bako for a few years. From what I gather, the man that was in the front of it all passed away a year or two ago.
Now, Bako has a 5.90 Nitro Comp class at the MM and HRR. That class is just as you would wish, FC, FED, ALT, and RED all running together. RENTF car count was up to around five cars in about three years time. I believe three of them are still running at both events. Brad Thompson parked his to focus on NFC.
