Front disc conversion/5 lug on 3/4

[ZZ4Blazer]

Hello all. New to fullsizes. IM sure this has been covered before, but looked around and couldn't find any concrete answers. Im working on a getting a 70 short bed. Hopefully I can get it tomorrow.

I believe its a 3/4 ton, cause its a 6 lug. Do the 3/4 ton have 6 or 8 lugs?

EDIT: I was reading around the forum more, and I believe it only a 1/2 now that its got 6 lug.

Being a 70, its got drums up front.

I want this truck to bag it. But, Im gonna make this a good driver also. Upgrade to at least front discs, power brakes, power steering, convert to 5 lug, etc.

I'd like to run a set of tubular control arms and drop spindles when I bag it, but would like to convert it to dics soon for better driving till i get the money to bag it.

So, Instead of doing it twice, Id like to use drop spindles as soon as I convert it to 5 lug and discs.

I believe that I can use 73-87 spindles, and I'd assume all the brake components from whatever year(bearings, rotor, pads, caliper).

What else has to be changed? Tie rods? I thought I read in a different post that the control arms on the 1/2 are different from the 3/4. Do they have to be changed to use the drop spindles?
