Technical Unity Spotlght Mount

I have a Unity 225 series spotlight. Need an A-Pillar mount for driver side. Anyone know where to source? Pic attached.

Thanks!

 

assuming this is for the Cadillac your spotlight should go on the door like my 49 Chevrolet. the mounts are specific for each car. you can get NOS ones on ebay with instructions and a pattern for where to drill the holes

 

You can still purchase the mounts new thru unity,,,
or use their site to get the part # and search eBay for the mount.
