I'm putting Sparco Grid Qs in my Challenger. What is the bolt pattern for the seat Mount bolts? I need to change the male torx headed factory bolts to a conventional bolt so I can tighten them down there is not enough room for a socket and ratchet. Thanks for any help.

Why would you think it is needed to change bolt head to standard from star bit? I added racing 5 point harness using the stock bolts for the tabs and they fit close and tightly

You can look at JEGS or Summit Racing for eyeballs that can be used. Ensure you get grade 8 for strength on all fasteners

I have new seat mounts and there is not enough room to fit an E12 socket in the space allowed. I can fit a box end wrench in the opening but that's about it.

I'm replacing the factory leather seats because I got tired of using the steering wheel to hold me in place while doing some spirited driving. I weigh 240 but have a 34in waist so the factory buckets give me zero lower body support plus the leather is slick. The weight savings will be nice too. I'm not using harnesses for now. I'll be sure to use Grade 8 bolts too. Thanks for the reply
