Front Seat Frame Support Removal 69 Camaro

I replaced complete floor pan and removed them prior too and yes it does make a big difference. I will leave them and change seats. if you really want those seats work on modifying seat.

I have seen cars come thru the shop without those sections in them, Makes it easier to install seats like yours. You could take some 14/16 gauge sections and lay them flat on floor going rocker to trans tunnel under the seat mounting area on the top of floor for extra strength and bolt your seats thru. Carpet will go over that with out a problem

If you remove those sections and replace with flat sheet metal you are going to weaken the floor structure substantially , the bends / folds/ box / structure gives it strength a flat piece on top another flat piece your just basically adding weigh.
my 2 cents

I always thought that, I've just worked a lot of pro built cars that did it and nobody ever complained. When we install the seats I will change the tracks to a flat universal style I buy.

Maybe they reinforced by other means that were not noticeable from inside or it is what it is we all do things a bit different and that's just another route a person / persons has chosen take on they're build.

As much as it would be nice to save the $120 I've got to spend for two new seat mounting plates on my project, I'm not sure I'd want to do without them for a few reasons:

1. They're pretty heavy, and likely impart quite a bit of structural support to the floorpan. If I was to take them out, I'd want to beef up the floor with something else.

2. They sit right over the rear mounting points for the subframe, so they stiffen the floor at the subframe mounting points as well, which is a good thing.

3. As thick as they are, they provide a solid mount for the seats. I'd hate to think what would happen in a crash if you only had the seats bolted through the floorpan, or through the pan and a thin piece of sheetmetal reinforcing.
