If you're planning to do towing, you'll want to keep that 3.73 gear. Also, you'll want to keep the full floater, as it's much stronger that the semi floaters. For disk brakes, check out the '01-'07 GM 3/4 ton trucks, the smallblock powered 3/4 tons used the same 14 bolt rearend with disk brakes, should be an easy swap.
Thanks for the info but I want to make sure I understand you correctly. Are you saying that the disc brake assembly on the rear ends of '01-'07 will fit onto my '77 full floater that I can then put under the'66. Or did you mean that it would be easy to take the whole rear end assembly off an '01 -'07 (brakes, rear axle etc.)and put it under the '66. I'm hoping you meant the former! But that would be too easy and no fun, right?
Thanks again for the info!
