The chassis is significantly different from the CR plans, a private set of 3000 plans taken off a survivor, Kirkham chassis, hitech chassis, and an original 3000 427 Cobra. Also looks like the suspension was bent to fit, brackets are not aligned, etc. So I will set it to what a factory 3000 frame is as I have access to an original and the current set of CR plans are pretty close on the critical pieces.
