Upper control arm swap?

[03JeepJeep]

Will a LBJ (73+) upper control arm bolt to a SBJ (-72) car frame bracket with out any modification?
Thanks

The UCAs mounts to the brackets on the frame rail. not the K frame The LCAs are installed to the K frame.

It will mount to the frame rail but it won't fit the 72 spindle because the ball joint shank is too large.

They swap fine with the car just not the knuckles.
