Nice of you to provide this overview. I think when you buy a Universal Seat, you should expect to possibly make some simple modifications. Cutting off the bracket after determining your need doesn't seem to be asking too much. Much better than having to add height or asking them to make a specific bracket for every application.
I think if I was to go with pro car I would get their universal bracket so would able to lower the seat more. I’m not the welder but I can tackle a few tacs
The Elite seats that I just bought come with head rest. Tomorrow I'm going to cut tabs to make it fit properly in my 79 Firebird. The Driver seat has a problem of the spacing fore and aft on the sliders being off and I had to use a bloody hammer to drive the bracket into place. Gonna try grinding down the ends to get a better fitment tomorrow.
I didn’t hear you say what car they are going on. I plan on buy a pair and I’m 6’ 3” and a fat ass to boot so I sit as tall as a 6’ 5” person lol. Keep looking into it the guy fabing my roll cage says it’s easy to make a bracket and move the seat back about four inches. This is all happening in a VW Bug.
I did the same thing, except tried to buy the Summitt seats. Didn't fit, no real brackets available. Bought the Procar's to do it right. Anybody want some Summitt seats?
