66 3/4 ton good for restomod?

[bigmoe]

I found a 65 GMC on an on line ad that looks to be in good restorable shape. I've been looking for one for a restomod project. I would be replacing the drive train with a more modern engine, tranny and rearend and updating the suspension (nothing radical), just power disc brakes and some lowering springs. I noticed the truck pictured has 6 wheel bolts and assume it's a 3/4 ton. Should I be concerned? Is this going to cause me any problems? What is the difference between the 1/2 ton and 3/4 ton? Just the hubs and heavier springs? Everything else basically the same?
