What size/length/thread pitch bolts for brace on NP208 transfer case?

[Gander]

My question is in the title. I’m missing one, and don’t want to have to take the other off and leave the brace hanging while I try to find a parts store or hardware store that has one. I keep seeing M16 online and then 1.5 or 2 which I guess is thread pitch and then 40mm or 35mm or 50mm plus is it just regular bolt with flat washer or flange bolt or what? All I know is I’m not going to pay $30 plus shipping on eBay for a couple used bolts. Help a brother out here!

I think he’s asking for the specs on the two bolts that hold the transfer case brace to the transfer case on the passenger side…

I have no idea and sorry not willing to pull one and measure

Let me look, I think I have a few extras. If so, I’ll send you one.

See I don't think I was thinking of the right thing which is why I asked for a pic. I was thinking of the braces to the converter cover. I happened to have the cover,the struts and brackets off my 75,I was going to check for him

If so that would be awesome! I’ll cover shipping, message me and I’ll give you my address.

That’s exactly what I’m asking for. Anyone know?

So it was like this when I got the truck. Shot motor mounts and loose trans mount and the PO had been driving it around like that for a while which is why I GUESS the case broke where that bolt threads in. Anyway, I found someone parting out a ‘88 Suburban and got the NP208 out of it to reseal and swap in but the suburban didn’t have the brace at all so no bolts. I’m trying to gather EVERYTHING I need before digging in and that includes this bolt. Looks like it uses a flat washer too. Anyway, anyone on here have the specs on this bolt/washer or maybe even one laying around I can get off you? I know there’s one guy on here saying he might have one.

If it is a 3/4 wrench size it's going be 1/2 13, check depth with a screwdriver I'm going to say 1.5 inches would work.

A 208 should be all metric hardware.

You can remove the remaining bolt and nothing should come crashing down. If it does there was another issue at hand lol.

M16 I'm assuming they mean wrench size in which case it will be a 10mm bolt. You are correct 1.5 or 2.0 would be pitch. 35,40,50 Is mm in length. When that info and a little investigation on your part you can get a bolt and washer from your local hardware store. Check depth of the hole with a screwdriver to get length,buy both thread pitches.

Hardware store and parts houses don’t carry the size. Fastenal/Grainger do but they won’t sell unless it’s a box of 10 and they want $25. Amazon.com can’t find anything but stainless and I figure you’d want grade 8 or higher on those bolts. Anyway, there’s a member says they’re sending me one and I really appreciate it!

Push comes to shove you can use Allen's. They are usually better than grade 8. Or m10.9

Those are beefy bolts and not a lot of shear forces on them for the size imo.
I wouldn’t be scared of not using high strength bolts.
I don’t doubt that Vato Zone and Homie Deport don’t have them.
Do you have a local hardware store with a good selection of nuts n bolts?
Assuming the bolt in the pic is the wrong size even though that looks like a 208 to me?

I replaced most of my bolts with new - so no doubt I have the (un-needed) originals in a labelled baggie and packed away. I have loads of this stuff priced right: free.

Someone is always wanting this stuff during one of Ohiostan's 9 months of winter when Hell is froze over again and I cant get to anything.

M16 would be the bolt size in this case, not the wrench size.

Any decent Ace or Do It Best or equivalent hardware store should have the bolts. The big home improvement stores tend to have terrible selection, unless you want non-graded butter bolts.
