Late model GM front seat tract frame

[jims5600]

I have a 2011 Silverado 1/2 ton. Has no power seat. My spine is a mess,have had 5 surgeries so far.
Anyway I need to shim under the front seat frame to move the front end of the seat up. That changes
the angle for my legs,makes it much easier for me.
For the life of me I can't see any bolts holding down the seat frame trac. There where always front and
rear bolts to loosen the frame trac to shim it up. Any help appreciated

If I'm not mistaken, GMT800 seats are held down with inverted torx fasteners and they're tucked down in the seat adjuster track.

Move the seat to the extreme front and extreme rear of travel and look right in the middle of the track. You'll see the inverted torx poking up.
