I am about to leave and head toward my Moms house where my 02 is. I have new headers, new tranny, and new gears to put in this weekend. My problem is I forgot to bring a lose header bolt for sizing (I am buying stainless bolts localy) So first question, what size and thread header bolts or studs do I need? Second the bolt where the leafspring connects to the frame I need the nut that goes there, any idea what size that is? Thanks for any help

 

never mind all taken care of

 

curious...
Aren't they the 3/8's standard thread they've always been?

 

i think everything on these trucks are metric....

 

yes, they are all metric.

mostly 7, 8, 10, and 13mm for anything you will normally do to our trucks.

I think I had a 7mm used somewhere, but im still up from the night before, and the alky still hasnt worn off, and im tired, so I could be wrong, ha.

 

The o2 bungs are 18 x 1.5. Try and find those!
