This car that doesn't have console gauges, (I am curious since mine doesn't either) what other factory options did it come with ? If you don't have any paperwork with it and are not sure thats ok. I do have the paper work for mine and since mine is a 08C of 1969 car it had the factory Tach and center fuel gauge as well as the spoiler package standard. The original owner special ordered it with the ZL-2 hood, tinted windows, AM radio, and basic interior decor group which had the stainless trim around the pedals and wood grin on the dash. He also specified the M-21.
I know a lot of guys who restore these cars automatically put the cowl hood on and console gauges, it sounded like you are trying to keep it stock, so thats why I asked. Thank you
