Does anyone know what the part numbers are for the mounting brackets for a Dual/Gate shifter. I have one for my car & the numbers are front (2) 5716 & 5717 and rear 5718. They don't quite line up with the holes where the original was?

 

Not 100% sure of proper numbers but your numbers match the numbers on mine which is, as far as I know, an OEM shifter. Mine has yet to be installed and will be installed into a non-Hurst car which did not originally have a dual gate or a floor shift for that matter. Also checked my 64-71 master parts catalog and it doesn't reference the dual gate before 1970. Hope this helps.

 

This is all I've been able to find for the 5716 - 5717 - 5718 bracket numbers. Mopar b-body, hopefully GM a-body as well??
