Tough one, may have to make something up yourself using some threaded B7 rod.

I think you're gonna be right... might take a standard 1/2 carriage head and shank and tig a 9/16 all thread to it

Re: 9/16 × 18 K20 carriage bolt

Do you need a 9/16-18 carriage bolt? If so how long? Or a 9/16 carriage bolt 18" long what thread pitch?

Is that 18" long? Where did you find it? It would be good for others to know

It's 8.5 inches long and is a NOS piece
link isn't showing the bolt I guess because it was the only one they had

Re: 9/16 × 18 K20 carriage bolt

Try it out on the spare carrier - I haven't installed my bolt yet but it seems tricky to do so after the carrier is in place. Has me wondering if there are differences between 1/2t and 3/4t s/m spare carriers.

Re: 9/16 × 18 K20 carriage bolt

Looks great. I’d be curious to see photos of the bolt in the carrier sans the wheel. Maybe I am doing something wrong but there wasn’t an easy way to get the bolt head into the slot.
