I CAN tell you that (without doubt...) 67-70 steer linkage is ALL different from 71, 72 linkage, AND those are ALL different from 73-up steering linkage.
HOWEVER...The control arms are all the same from 67-72. Your 72 upper AND lower control arms will bolt up to your 70 cross member.
67-72 Pitman arms are same,(Power steering, remember manual takes a different pitman arm, 68-72 manual pitmam arms are same, not sure why 67 is NOT included. 73-up pitman arms are another part number
67-82 Idler arms are ALL same!!!
The thread sizes on the threaded end of the tie rod ends MAY be the same (My experience tells me, IT IS NOT), BUT also the tapers on the tie rod ends are not the same. The tapers are larger on the 73-up tie rod ends. 71 and 72 tapers are the same , BUT also different form 70 and earlier.
I do NOT know if the aftermarket makes "conversion" tie rod setups for the 71-72 spindles. The only way I know to use the 71-72 spindles is to use ALL 71-72 steering linkage...

Thanks for the info and confirmation. Everything I have read and seen on this site as well as in catalogs - the steering linkage is different from 67-70 to 71-72. But like you said the pitman and idler are the same for all years.
What I can tell is the threads and size on the tie rods are different on the years - so either have to replace the whole linkage or get outer tie rods for a 71-72 and a thread converter. However, the CPP thread adapter says it Accepts 73-87 outer tie rods and 63-70 inner tie rods.
So questions:
1. Are 71-72 outer tie rods same as 73-87? to be able to use the thread adapter by CPP. Vs changing completely over to 71-72 linkage
2. Is the engine crossmember the same 67-72?
3. The tubular control arms are different part numbers 63-70 and 71-72? Does this have to do with the boots? What makes the tubular different from stock control arms? The stock control arms are the same for the years.
