68 to 71 cab differences
 

I'm sure this has been asked before but the search option doesnt always work. Maybe because I'm on my phone. Anyway , other than the parking brake lever and obviously the vin, is their a difference in the cabs? I know the front clips are a little different but is the cab its self different?thanks

This is NOT a for sale post... However, I know where there is a perfect 67 cab with a small window in sealer. I'll send you a PM. No money for me in this... I am just trying to help another out....

Re: 68 to 71 cab differences
 

Besides the above mentioned differences
Most Important is
67-68 cabs use a completely different fuse box than 69-72 cabs and they are not interchangeable. So you must use the correct year harness for under dash harness, engine harness & forward lamp harness for the year of cab you are using or cut the fuse box opening off the original cab to graft to the donor cab.
another is
The 71-72 cab uses a different gas pedal mounting than 67-70 cabs.

Thanks for the input guys thats just what I needed to know. I just bought a 68 but its being shipped so I couldn't compare it to the 71 cab I've got. Thanks again
