Spindle swapping 67 - 73?

[stateamind]

Ok guys, here's the deal.
My original plan was to take the complete front x-member from my dads old 73 1/2 ton and slide it under my 67 c-10. Instant disc brake setup ... wrong. The 73 has been sitting in the weeds for the last 15 years or so. So, i was not suprised to find, after removal, that the lower control arms are in sad shape. Rusted is not the word here, lol. I've read post on here before abt just using the spindles and changing out tie rods and ball joints, etc. My question is what parts do I need exactly? For what years? All parts off 73 are good, except for lowers. 73 was manual steer and I have a pwr gearbox from 70 c-10 on the 67. Any help here guys would be greatly appreciated. Mike
