Hi:

I have to ask this question since I have always thought the difference between chevy and GMC has been in slight differences in options and minor sheet metal differences. Now that I have acquired my first GMC and I plan to invest considerable amount of time (and perhaps money, hopefully not too much!) I thought to get this out of my way. I have a 1953 GMG 3/4 ton. What is the differences between Chevy and GMC 1/2 tons and 3/4 tons? Of course besides being 1/2 and 3/4 tons and different suspension set ups in relation to their gross wt.
I just learned that chevys are considered AD and GMCs are new design (ND?)? Also I learned that GMC is positive electrical versus chevys are negative ( So how can I jump start a GMC, connect the leads backward?!) Does online brake kits, suspension parts, cab patch panels, and etc will be interchangeable between chevy and GMC? Please let me know about any differences that you know then I would save some time and money on my upcoming 1953 GMC 3/4 ton project. I plan to keep the truck 3/4 ton.
I am sorry of this is a very basic question.
Thanks
