I have a standard package.... but I will and have put the motor trans up / down / back / forward.....often at no extra charge.
One of the benefits of no torsion bars and the more compact rack and pinion is the ability to move things around if desired.
Having a hot rod for some of us is like when we were growing up and built everything we were shown in the Erector Set guide.....then it was time to build what we imagined.
