His bolts on the tailhousing like a normal hurst does. And his has shifter arm alignment bolts. Plus a bolt on stick.
Yours is an offshoot of the hurst.
It’s a hurst-Indy. Universal mount, no bolts, non Bolt on stick.
Indy shifters were marketed by Mr. Gasket. They didn’t use the hurst body until hurst acquired Indy shifters in a big merger. IIRC Holley owns them all now.
What you have will work now.. put the reverse rod on first.

I also noticed your trans input shaft has 3 rings on it. That would indicate it’s a 3.50 first gear trans. And the weakest too. It won’t handle any abuse.
