1970 Truck Bucket Brackets

[70LonghornCST]

Hi all!
I need to tap into the wealth of knowledge on this board. I recently
got bucket seats from a 70 Blazer and it came with the Blazer seat tracks. However, after reading many threads on here, and setting the seats into the cab of my truck, I am now convinced that the Blazer seat brackets are about 3 to 4 inches too tall. And I know how rare the actual truck bucket tracks are.

I got the aftermarket seat brackets for the passenger side. They are lower than the blazer brackets when compared. I did set the seat with the aftermarket stationary brackets into the driver position and it seems to sit about the right height.

My real question is has anyone used the stationary passenger brackets on both sides? I have the gas tank in the cab and do not intend on changing its location.

So, if the seats are mounted in a location that works for my reach, should I just use the aftermarket stationary brackets?

Or, are there any mods that can be made to the blazer driver brackets to make them fit correctly?

Any help, ideas, or wisdom would be GREATLY appreciated.
