Gentry,
I too enjoyed your visit,,, come back anytime.
If you do the S&W 10 point kit,, that is a great foundation,, you can either add the funny car cage kit to it or go with a full containment seat... I would get the kit first,,, then decide which way to go after you tack in and mock up the main kit... I would also buy an extra stick of the same material 1.75 x.120/1,25 DOM so you will have if for extra braces.
I would also get some .125 plate and some 1.00x.120 dom tube so you can make tubular and plate gussets as needed.
You may also use the 1.750 tubing for rocker/door sill bars as well. I prefer rectangle tubing for frame connectors on
unibody cars,, but round does work.
Call or stop by.
Charles
