My pleasure Michael. I'm a bit larger than 6'2", more like just shy of 6'6", so all the leg room I can get is vital. That is actually part of the reason I designed the back brace I did out of 1x2 for my chassis. 2x4 would have been stronger and I would not have to reinforce down the tunnel via a mess of tubes, but I would also lose precious space for exhaust and headroom. Exhaust would have to run under the floor and the floor would then be about level with the top of the inner rocker, no good. I have recessed my floor and gained about 1"-2" of headroom from a stock Dart floor. I'm also going to be reworking the mounts on the Viper buckets to try and gain a few extra 1/16th's. I'm hoping to be able to tilt the radiator back as well, give it kind of a Corvette C6R feel. I'm not 100% sure the AEM unit is the UEGO but it could be. I've been talking with the guys of Roe Racing and Woodhouse Performance about electronics, and they haven't mentioned the UEGO, but that could be it.
