Need special bolt for jump seat for 66 burb - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**1966burb** · 04-13-2017, 10:58 AM

I know this is a long shot, but throwing it out. I need one special bolt for the pivot or hinge point on my passenger folding jump seat on my 66 burb. The part that is special is the shoulder under the head of the bolt. I have searched shouldered bolts and have found nothing close. I may have just make a sleeve that slides on the bolt but OD dimension is odd so it will need to be turned down on a lathe. Hoping someone has a rusted out or broken frame in their special junk that has the bolt I need.

Curious to know if the bolt in your pic is stripped and unusable? if not and it's just a bit rusty it would be easy to restore it to like new condition. Or is it that you only have one and need more than that?

This is the good one. Other one is broken. J

Thought that might be the case, good photos and drawing btw. Agreed that to match exactly would mean either someones rare spare parts bin or salvage yard. The alternative would be to find something that looks the part and functions as the stock piece with little to no modifications. I'm sure others will chime in too, here is a link to PIC which has both stock sized and custom made precision shoulder screws:

Still looking for one bolt. I may just have to find something close and have it machined to match.

i know of a spot where such a bolt is to be had!!! is it the bolt that attaches to the front two curved legs for the jump seat? if so i can hit this place up this week end...

I would just get a couple 5/16" x 1/2" button or pan head bolts, have a couple sleeves machined to ~.314" ID x .440 OD and .125 long and slide the over the bolts. That is not ideal but should last for quite a while.

**1966burb** · 07-13-2017, 01:11 AM

Yes, thanks, I have already got the bolts and was headed that direction with making some sleeves. j

Here are some pics of the bolts in seats.

One bolt looks correct for sure. You would want to soak those with PB Blaster or sometime to keep from breaking them off during removal. J

One bolt is holding me up. I could really use one. Don't make a special trip. I have a regular bolt holding it in place for now. J
