I have converted 2 trucks. First was a 70 6 lug truck w/ power drum brakes and the second was a 72 8 lug suburban w/ power disc brakes.
For the 70, I used a local vendors kit for the front which bolted in completely and for the 72, I just had to buy their 3/4T to 1/2T conversion spindles (I opted for the 2 1/2" drop).
For the rear on the 70, I just need the axles and brake drums but for the 72, I needed a complete rear end. 1/2 ton and 3/4 ton rear ends bolt in the same on the trailing arms trucks but you need to change the panhard bar (I don't know about leaf spring trucks).
I can tell you that the fittings on the 93 power steering box are different and you will need custom hoses unless you use the 93 power steering pump. You will also have to verify the frame width on the 93 is the same as the 67 and the placement of the cab/bed/radiator mounts (as well as the wheel base you mentioned).
If you have more time than money, converting the 93 might be better but it seems like alot more work than simply bolting the other stuff on IMO.
Hope that helped and good luck with your project!
