LCA and Spindle fitment Help

I have a pair of standard 67 LCA small U joint , small bolt pattern ,listed for sale.
@Rassnasty82 Has paid me for these and before I ship to him I want to make sure they will fit his car.

He say's he has a 69 Cuda with large Ball joint UCA, 4 piston calipers, Possibly from a 73 Duster "?" -AND LARGE BOLT PATTERN hubs.
Hopefully Rass will join in with more info if needed.
What year did the bolt pattern change ,when did the brakes change , and did the spindles and
LCA change also ? Thanks for any info on getting this lined out !
