That looks like the repro 69 Camaro round stick. I have not had one in my hands yet but I think it is shorter than the OEM A body Hurst handle; not that shorter is a bad thing. 🙂That is a OE type. Like others have said it was drilled out guessing for reasons of removing the lever, messing up the retainer, then fixing with the bolts, Atleast someone put some thought into it instead of welding it together like some seen at swap meets. I went out & got some pics of my over ther counter Comp Plus to show the differences. The bolt plate has fine threaded holes (5/16-24) Even though it was new I replaced the bolts mine has with actual grade five since the included ones wasn't marked on the heads (all included bolts was replaced cause none were.) The stick is the round one I picked up years back.
