Thanks folks, I gather you mean that a sub-frame connector joins the front half with the rear half so that means that your chassis is in two pieces rather than the one, my monaro and kingswood has a chassis rails that looks a lot like your comaro and firebird setup, a monocoupe body so to speak, I'm just a bit confused as to how you handle the installation, as I would have to make my own connectors, no one manufactures them and it means designing them too, I would like to find out exactly where they bolt to or weld to and I gather the end of the rails, so I figure mine would come out at a 75 degree angle, weld to the chassis then kick up, back and twist to the lower suspension point, does that make any sense?
