Lets see those pics of the first generation 1969-1970 Attex 6 wheelers back when they had the Baker Hill transmissions before the T-20's. Heres my Attex 297 right after I picked it up and a shot of the frame of my ST/300 racer. Thats a Baker Hill 7000 transmission that I removed the reverse unit off of for less weight and the engine is a freshly bored and rebuilt JLO/Rockwell 440. The first generation Attex machines can be identified by the exhaust exit location (on the very rear of the drivers side of the body) and they're narrower than the 71+ machines.
