Does anyone recognize this dual gate

[JoeC]

That looks like the Duel Gate shifter that Hurst sold as a column to floor shift conversion kit. They were made with different lower brackets to fit the shape of the floors for different car models.
Some lower brackets have the bolt tabs on an angle to fit the trans tunnel.
The shifter came with a plastic console that you had to trim to fit your floor

I have one for a 69 Chevelle and mine has different lower brackets then that one.

Yours looks like it fit a car with a higher more flat trans tunnel shape
