I saw a reference to doing this swap elsewhere on this site, but there wasn't much guidance posted.  I could really use some advice.

I want to replace the stock '72 calipers with '74 up calipers since high performance pads are readily available for '74 and up calipers (and are needed for "track days").  I'd rather not change the control arms or tie rods.  What is involved in making this conversion ?  Thanks. Leo
