ORIGINAL Suburban seat hold-down bolts... need specs

[Brad54]

Does anybody have an original Suburban seat hold down BOLT that I can get the original head and shaft length dimensions from?

Thanks,

I will pull one of mine today and post a pic for you. Keep in mind that I have flat washers and locknuts on mine. The bolts originally had a square pice that was formed on one side to go over the frame tube, and a wing nut.

My bolts are 1/4" diameter 2" long with 2 flat washers and a locknut. Here are some pics holding the seat down

Thanks.
I've got regular carriage bolts on mine--the originals had a much wider, flatter head--that's what I was trying to find.
Some were for sale here last month, and I missed them!
The seller had already shipped them when I asked for the dimensions, and the buyer hasn't replied to a PM.

Regular carriage bolts will work unless you are going for originality. I've actually tightened mine up too much once that it started to bend the floor plate up. I feel safer with the locknuts over the wingnuts. Atleast they won't lposen up over time with vibrations etc.

Ok. Finally found one of my originals. Not a lot of difference between it and my newer one except that my newer one has a shoulder where the original doesn't. I've also got my rear seatbelts held on with the locknut until I can get them into the floor as original.

Hmmm... interesting.
The ones that were for sale in the classifieds had a wide, flat head.

Not sure if the size of the head has any importance, just the sizr of the shank that slips into the bracket. Maybe someone on here with an all original sub can shed some light on this. I will check myself and let you know.
