FFR Seat Slider - Nutty bolt

[Kivyee]

So I'm in the process of getting a harness installed, and discovered that the rear bolt/nut to remove the seat from the slider track have a hex key head that's inaccessible, which means theres no way to get the nyloc nut off. Am I missing something or am I going to have to cut a slot in the bolt?

Here's the bolt in question -

Thanks in advance for the sanity check!

Might need to take the whole mount off, slide the slider forward, in order to get to the head of that bolt.

It was put together so it has to come apart. Meaning to tighten the nut the bolt would have to have been held. Is there room to grab the head with vise grips? Push comes to shove maybe unbolt the whole thing from the floor and take it out of the car to access the bottom. Another thought if there is that limited of a space that a regular Allen wrench won’t fit maybe cut the short end of the wrench down to fit. Having been a mechanic of one nature or another for 50+ years I’ve had to *******ize tools numerous times to fit odd situations.

Just had another thought there may be an hole in the lower track that would allow access. Might have been what Chewy was working toward.

Unbolt the sliders from the car with seat attached

Thanks for all the comments guys! Unfortunately the sliders were secured with a nyloc on the top side and was in accessible with the seat in place. Thankfully I could get an allen wrench into the 2 front ones once the seat was slid back all the way, and one of the other rear ones actually was jammed in which prevented it from rotating . Ended up cutting a slot in the bolt and that worked well enough to remove the nyloc the rest of the way.
