Bolts

[Original Smith]

I need to know if anyone knows of a company who can do a short run of special Model T dust pan to frame bolts. These were used on the early cars in the teens. The part number is 3088, and is 1/4-28 X 9/16. The head and nut are 3/8 square, and there is a cotterpin hole at the bottom. I don't believe anyone is reproducing this part.

Larry,

What quantity is a "short run"?

[Jerry VanOoteghem]

Are you interested in having these made or not? How many do you want?

[Original Smith]

I'm not really sure what a short run is, but I am guessing 100-200. The other thing is I'm also not sure how late they used these bolts. They have a 3/8 square head and nut, and the bolt has a hole for a cotter pin.

[Jerry VanOoteghem]

Yes, that probably constitutes a short run. But it's more than I would consider making myself, which is what I was considering doing.

(I'm still looking into a couple of possibilities though.)

Larry,

Please fill in the missing dimensions and have a look at the dimensions I've shown. The heads will be a nominal 3/8", meaning they will be slightly undersized, per industry standards.

I am getting an original today, and will be able to supply the needed dimensions. I have some on my cars, but don't feel like removing them. Thanks for all the help!

[Original Smith]

Thread length 7/16" , Cotter pin hole 5/64"

[Original Smith]

Bottom of bolt to center of cotter pin hole 3/32"

[Original Smith]

Does anyone have information as to when they stopped offering this part?
Let me know how much $ for 100, and how much for 200?

[Original Smith]

Here is the nut details. 3/8 across the flats, a slight chamfer on one side like most square nuts. The thickness is .187".

I was hoping to be able to insert the details you need on your sketch, but don't know how to do that. So, I hope you now have what you need.

Larry,

Yes, those are the dimensions I needed. Thanks. I'll let you know how it goes.
