Cab mounting bolts?

[77 step]

Hey guys,

I am installing new cab mount bushings, and was wondering if anyone knew offhand what size the blind nut is in the channel in the cab. 

They seem to be 1/2" diameter, but a 1/2-NC bolt doesn't want to start very well.  This is a replacement cab, and is off a 2wd, mid seventies rig.  I removed the old cab, and threw the bolts a couple of years ago, so I have nothing to compare to.    

I don't need the length measurement, just diameter & pitch.

Thank you in advance for your help, I thought it would be worth asking before  trying to chase the threads.

IIRC they're standard  1/2-13 (I'll double check the pitch when it gets light).

I'm replacing a set today and will be ordering all new bolts. I'll let you know For sure what they are.

Thanks, guys.

Donut, that's what I thought too.  They may be messed up from the condition the bolts were in when they were removed, along with sandblasting, paint, etc.  I just didn't want to use the wrong tap to clean them.

Vile, I appreciate it.  I will be checking back to see what you find.

I just checked, 1/2-13.  at least that's what worked for me.

Mine are 1/2" - 13 also

The bolts are about 3.75" long stock

I appreciate the posts, guys.  Thank you very much.  Now I can stop at the hardware store on the way home and pick up some hardware (with confidence).
