Six lug drums changed over to 5 lug disks...

[KrashMan454]

I Pick up a couple 68 SWB trucks yesterday. Planing to take the best of both and put one together. Today I was checking out the local junk yard and ran across a 72 with all of the 5 lug stuff under it. What do I need to pull off? Do I need the upper and lower a frames or are they the same? How about the tie rod assy? I heard that you need the 72s because the 68s tie rod don't match the 72 spindles. What about the center link? Please give a break down of what I need to pull to make the swap. Thanks in advance for any advice! Krash!
