Hi Rodney and welcome to Stovebolts... I looked through the limited resources that I have in my "truck library" and couldnt find an answer for you HOWEVER... since you mentioned you recently purchased a truck (by the way I've always been a fan of the 65-66 Chevy's) there are 2 valuable references that you should have on hand... first is a "1960-1966 Chevy/GMC Truck factory assembly instruction manual" which last I checked you can get for less than $20. I got mine from Golden State Pickup Parts, Inc., a few years ago so they may be less than that now. The second is a free catalog from LMC Truck Parts... (website is "lmctruck.com") both of these sources are a "must have" in my opinion as they are loaded with diagrams and information that you'll need ... if not today or tomorrow... you'll eventually need it. Best of luck on your experiences with your cool truck as well as here on stovebolt.com. I have a 65 4x4 and would love to see a couple pics of your truck sometime.
