I would post in interiors, but I thought many of you surfing performance section use non-stock seats in your rides.

I'd like to install my front buckets in my 68 today, just unsure of what grade of bolts and hardware I need for install. The seats are out of a 93 Firebird GTA. I have some flat stock to use as fat washers on the underside of the car to spread out the load.

Any ideas and recommendations would be helpful. :thumbsup:

Thanks, John

John,

Be sure to post up some pics when you have them in. I have some seats out of a 93 camaro that are going in my 69.

Thanks,
Brian

I used grade 8 bolts with grade 5 fender washers. I think the bolt size I used was 3/8". The force it would take to shear 4 3/8" or even 1/4" would be very high. Use nylon locking nuts!

Grade 5's easily good enough unless your mounting a racing seat with a 5 point hitch attached then I would use 8's.

Thanks for your input, guys. :thumbsup:

I went with 7/16 bolts, and thanks for the tip on the nylon lock nuts.

'Cause you asked, here's a couple of photos...before and after. :)

Just need to install the RCI harnesses, and we're legal....sort of.

most stock seats are held in by 5/16" grade 5 bolts.
