Jaz aluminum seat mounting

It's too bad the floor hump is going through the middle or you can just run a straight edge from one side to the other and bring up the inside side of the bucket seat. As it is it's just matching the outside Mount which is raised to catch both ends of a bench seat and making that the same on the inside. When I made my bucket seat brackets out of some old van seat brackets I had to shim the inside of both the passenger and driver side. And I think the front I had to shim more than the back. But ideally like in your pictures if you get the floor leveled out or a bracket on the floor then it's just even from side to side and you can mount it straight down.
