Why is there only 4 nuts and 4 washers and 8 bolts?

This bolt kit is for one seat. 4 bolts to bolt sliders to the seat. The other 4 bolts with washers and nuts are to bolt the sliders to the seat brackets.

Do you need two hardware packs to install seat base and sliders or will one pack do both?

I bought this more than a few years ago, but I only needed one pack to do both the seat and sliders.

Will these fit NRG seats ??

They should, they are all pretty standard on the bolt size and threading used

If i buy these are they for sparco seat brackets?or for any brackets

Will work for sparco and sparco replica

Worked perfectly for car or sim rig

The intended use for this hardware kit is to mount a Sparco seat to a frame rail. In my use-case, it was a bit different. I mounted the seat to a frame rail atop my simulation rig (sim rig). Bolted well, with no flex and allows actuation of any seat movers.

Waiting for today

They look good looks like they’re strong. They well hold everything and need to be held. I just haven’t had a chance to get any to put in my vehicle due to the weather and my age and trying to find somebody will help me put in for me.
