AJ's team at Bob George Racing did my chromoly cage for my 71. Tucked in around my door panels and through the package tray right on top of the frame. I wanted it sleek and tight to the body and they delivered. If you're spending big money regardless do it right. Buy once cry once. I opted not for a removable cross bar, e body seats are useless as is so it wasn't worth it for me.

One thing that's an absolute, you need padding on these cages especially for the street or else come accident time they become a weapon as you bang around in your seat without a helmet.
