1969 Roadrunner K member bolt size and thread.

[41dodge]

Removing my K member, one of the bolts broke off and I'm having no luck using an ez-out so I may have to drill most of it out then run a tap through it. Can anyone tell me what size bolt it is and the thread pitch so I can purchase a tap?

Thank you in advance,
Vic, 41dodge

Thanks. I'll be looking for one today.

If you can drill a hole through the bolt, or what's left of it, and douse it with penetrating oil.
Use a die-grinder to wallow out the hole as much as you can without hitting the threads.
Keep the area soaked. The vibration from the die-grinder may loosen up the remaining piece!
