Years ago I looked into doing this because I figured it would be cheaper for me to take a 71 hub assembly to a machine shop and have it reworked to fit my six bolt 70. The nice man explained to me the amount of labor involved to even try this. It's not even close to economical.
There's lots of conversation kits out there, and at very reasonable prices.
Is your truck a daily driver, or used for towing?
The drums work fine for occasional drivers.
I guess it comes down to if its worth the cost to you to do the conversion.
It will be an occasional driver, just a time or two per month, and I live in Canada, so the driving season is shorter than most.

I wasn't to run a certain rim is the reason for 6 bolt conversion.

I have a friend who owns a machine shop, the labor would be a swap for beer or favour.

I have not noticed any difference in the casting of the drums, I believe disks and axles are machined, I can't imagine them being different.
