273 Commando or Not?

It has a 30 below AB 14" wheels no sway bar but came with 2 other K frames I will have to look at them.It came with 4 dashes some with gauges and some with out. I found the original build sheet under the back seat mostly chewed up but you could read 4.63 gear ratio 2 tone paint silver and black. There are holes in the fenders for the formula s emblems but no emblems. I bought the car as a grocery getter for my wife but as usual I have gone over and am know try to get it back to as close to original. I am attaching a couple pics
