Hey gang. What is the bolt size for a 1970 440+6BBl K member? The 4 bolts that mount it to the frame rails. Thank you. Bill.

Bill, telling you the size and thread pitch of the threaded portion of those bolts will not help you. These are specialty bolts with a tapered shoulder that is important for proper positioning of the K member. The size on a V code car is the same as any other Mopar of that era. You need to shop for a set of good used or reproduction K MEMBER BOLTS. There is often a member or two with them here on the parts for sale pages, and failing that, on ebag or Amazon.

As a matter of fact, I am surprised that you did not yet get an offer to sell you some, based solely on your question.

I've got k member bolts that can be had cheap if you need them. PM me..if you need help.

Thanks
