IMO, a heavy spec Chevy C 80 should be listed with the same GVW as a GMC, why it's not, is a mystery to me. Side note, a 6500 is just a higher powered 6000, ( 478 vs. 401) otherwise same available axles.

Although I didn't read the pages above, I did check some brochures online and I'm beginning to see what you are saying. One '64 brochure stated GVW's up to 25,000. Although I'm sure that they were referring to single axles only. Another brochure, which was probably '65 or '66 stated GVW's from 25 to 29,000.

Also discovered another thing. Seems like most singles axle 80's, '63-'66, did have the narrow fenders with the lighter fronts. I guess all the C-80's I've been observing online through the years have been either '60-'62 or tandems with heavier fronts and wide fenders.
