One easy way to eyeball used covers right off is that the hole for the rod is CLOSE to the middle of engine on a 2bbl carb engine.
And on outside closest to valve cover on a V8. Lots are selling used 22bl choke covers as 4bbl.

Have several dozen original 4 bbl choke boxs. The lined "restamped 8097" version was actually done so by Rochestor Products. Can't say I've seen such a line stamped choke stove on an automatic '70 application & have owned two original '70 YZ engines & examined several others.

So how do I determine what it is? Do you have a 0097 for sale in good condition. I have a new repop but would like a nice original. The 8097 might not be original

2bbl and 67. Had the lever coming out on the firewall side
68 up had the lever on the radiator side

It also looks like there was 2 different covers for 67
The 3 67’s on the top row have a different slot where the rod enters. The lower 67 is like the 68up.
No wiggle in the opening see the left one it shows up good
And a 2bbl lower left for comparison with long rod
