Help K member bolt size

[lawman340]

Does anyone know the correct bolt size for a 1970 Duster K memeber.....I know it is a special bolt with a shoulder but I am just talking about the thread size. I have read 1/2 inch coarse and 5/8 inch coarse.....can anyone shed any light on this.

I would bet they are bigger than 1/2, sorry I have no way of measuring without removing one. So far as the shoulders, the holes are so sloppy I doubt that would be an issue.

Oops that was a little more in the sec LOL I fell asleep and then I went snowmobiling the next morning. It's an
1 1/16 socket that fits it.

I remembered having to send my wife down to the parts store to grab the correct socket for me. Damn sure had to be the only one I didn't have!

I believe 5/8" coarse.

In my early A's, the 4 K-frame mounting bolts looked like a non-standard thread-form, more like a light-bulb thread if I recall. Might have been buggered up, in which case I should know before the K-frame drops next time I lift the frame.

How long is the 5/8-NC bolt for the k frame mount?

These are both MOPAR people.
Good sources.

(IF you really need to know the length, I can measure one later?)
