It was on track about three years, then i was stripping it to the frame for paint and in the process i thought I'd try fitting one if my brother's wheels to see how the offset was and it snowballed. Im 5'11 and the helmet fits right inside the triangle about 1" from the ceiling. I have the seat set very low, the back is about touching the floor. Here's a link to some pics over theclast five years of working on it : Pics And a link to the last time i drove it The Glen I do have a Hans but thanks for the offer. Everyone's enthusiasm is definitely helping motivate me to finish the body and get it painted and back together for spring!! Thanks Guys!!
