This keeps all your steering parts correct for your 69.

You have a couple options:
1) locate a 71-72 centerlink and use all 71-72 inner and outer tie rods.

2) use your original centerlink and convert to run 71-72 outer tie rods.
This is where it gets tricky.
Your original 69 outer tie rods won’t fit so you will need 71-72 tie rods to match your 71-72 spindles.

Except your 69 outers are LH thread and 5/8” diameter.
The 71-72 outers are RH thread and 11/16” diameter.

So to connect these to your 69 center link you have to:
a) buy a 5/8” to 11/16” conversion tie rod sleeve.
b) use 67-70 outer tie rods at the INNER location. (LH thread)
c) buy 71-72 outers to fit your spindles. (RH thread)

If you had purchase 63-70 conversion spindles
You could use all 67-70 steering parts.
But you are past that now.

CPP, PerformanceOnline, Edelbrock, QA1, and Pro Performance all sell the tie rod adapter sleeves.

thank you Keith I think it would be helpful if you edited your original thread something to this effect:

2) 67-70 truck owners can now purchase "year specific" standard and drop spindles, from many aftermarket suspension vendors.
* No need to change ball joints.
* No need to change center steering link and tie rod ends.
* These new "conversion disc brake spindles" are a true "bolt-on" mod to add disc brakes to your truck.

knowing that may have pushed me over the hump and I may have just bough a whole used 71-72 crossmember with control arms, spindles, and steering link

now it makes sense why my parts pimp always just swaps the entire 71-72 front end on to the 67-70 trucks

please note I am not complaining or ranting just trying to help others out, and the more we know the better
