Which Starter Bolts Do I Need?

[67mbsc]

I have a 1968 C-10 with a manual trans, and a small block engine. The starter has a cast iron nose, and the mounting bolts go thru the nose, into the bellhousing, and NOT the block.
My question is, where can I find the correct bolts, as each of them is different. The bottom one will have a large shoulder, the middle one has a smaller shoulder, and the top, that bolts thru the bellhousing, into the starter, may not have any shoulder!
I have NO bolts right now, had my local dealer look, they even called the factory, and nothing came out!

I want to keep the starter that I have it's new, and I don't have any block mount starters right now!
The hole for the bottom bolt is almost 7/16". Is there a bushing for this?
Thanks,

They are all 3/8 bolts with no bushings. The starter nosecone indexes into the bellhousing for alignment.

I just stick a pencil or screwdriver in the holes to find the needed length and install appropriate length 3/8 bolts from my bolt can or new.

Also, I agree with you. The cast iron nosecone starters are outstanding units. I like the way the mount as opposed to the type that bolt to the block.

without a serious shoulder, the bottom bolt is really worthless towards lining anything up! Will the one top bolt really put the starter in it's place? The middle one, with a normal knurling, would work for the middle hole.

The raised lip around the starter nose housing indexes into the bellhousing and does the locating.
