68 3/4 ton 8 lug Disc Brake swap

[19Hoosierdaddies68]

Hello,

I have a 68 3/4 ton 8 lug with drum brakes and coil springs all the way around and would like to start by swapping to disc in the front and stay 8 lug to be a little different. I would eventually like to bag the front and rear. In the front I am thinking about going with a drop spindle to get the desired drop with the bag, either 2.5 or 3". What do I need to do the swap? I have found a local craiglist source who says he has a dics setup from a 69 3/4 ton for $40.00? Sounds like most of it would need to be rebuild anyway so all I would be buying would be the standard disc spindle, which I dont think I will need if I am buying dropped sindles. Are the upper and lower contol arms the same between drum and disc? If I am buying the drop spindle could I just piece the rest of the disc brake components from a standard parts house, Autozone, napa etc.? As in rotors, calipers, hoses, booster... I live in Southern California and near CPP ( I have already used them for a brake swap on my 67 Camaro) so if I can get any parts there that would work. does anyone have a parts list to make the swap easy and on the cheap? What years if any allow me to run my control arms?

I also have another So Cal craiglist source who is selling a complete ("everything I need and ready to run") 8 lug disc setup for $450 which seems high. I believe he said I would reuse my Upper and lower Control Arms. he also has the lines and booster for another $150 I think...

Let me know your thoughts. Thanks in advance.
