K-Frame Bolt Size

Hi guys, I've got a quick question that has been hard to answer so far:

I need to know the size/pitch of the big K-frame to frame rail bolts!

I sold off my suspension for books one semester, now that I've graduated it has paid off with a job that will let me restore my Duster in a somewhat timely fashion..but she's gonna have to move 2200 miles with me! Need to fab up some sort of dolly to get it on and off a transport truck...I'll become more and more active as my project comes out of its comatose-like state!

Thanks in advance!!
Travis
