LCA from a '72 Drum to '73 Disk

This was a comment in my build thread of my Duster:

"Do a little checking before you use the earlier LCA's with the later spindles and ball joints. I did that once, and the car wouldn't turn in a 40 acre field! @hemi71x or @72bluNblu are both members with extensive knowledge of what works and what doesn't as far as suspension parts."

Complete front end from a '73 Dart but the LCA are banged up so I planned to use the LCA from the '72 Duster which are very clean (new bushing needed of course).

Is this a problem? I have the '73 UCA, Spindles, gear, torsion bars, ect... everything but the LCAs which would come from the '72 Duster.

Thanks,
