Quick '71 B-Body Disc Brake Swap Question

Im about to do the '73 A Body disc brake setup onto my '71 Satellite. Ive done this swap on other A-Bodys and '68-70 B-Bodys but never a '71 B-Body. Is it the same as a '68-70 Body? I can keep my original UCAs and LCAs and just change the spindles, right?

Also, will a sway bar from a '68-70 B-Body work on the '71?

Yes on the spindle swap, no need to change control arms.

Sway bar.... breaks down on pre 69 and 70/72 as far I recall.

Original disc was all the same for 70-72 B and E.
