Thanks for the compliment and suggestion. It's 145" wheelbase. FWIW, I built the car by plans from S&W Race Cars, but since .058" 4130 was difficult to get in all the quantities and sizes I needed, I built the car with .120" D.O.M. (to meet .118" wall NHRA specs)......and yeah, she's a plump thing.
I don't recall a diagonal in the forward "box" on the 200" car plans I used and abbreviated to 145", but I will take another look to see if I missed something. Certainly easier to add now than to repair.
Your profile lists Gateway as being your track. Is that the St. Louis' track which is now Worldwide Technology Raceway, or whatever it is called now, or is it a Gateway somewhere else?
