Kelsey Hayes brake spindle?

Ok well I ordered qa1 handling kit 2 front suspension, but ordered the small ball joint UCA. I think I'm going to send those back order big ball joint UCA and get 73-76 disc spindles. I figure if I'm going to build it might as well build it as tough as I can,

One more question cuda68scott. I've heard there is 2 types of steering linkage. I would prefer the bigger one. Will these spindles accept the larger tie rod ends?

Thanks for all the info

I am not entirely sure but am thinking the tie rod ends stayed the same after 1972 so it shouldn’t matter. But... you might want to do a separate post to get some other expertise.
