Return engagements or "recreations" happened a lot more during the golden age. It was actually more rare to have a revival that deviated substantially from the original production; some of that may have been due to the fact that the original creators were still alive and working, or the revival came in as a tour stop (aka, the set was scaled back).
Off the top of my head in no particular order:
Pal Joey
On Your Toes
West Side Story
Oklahoma!
Fiddler (all pre-2006 revivals)
Dreamgirls
A Chorus Line (2006)
Mame 1983
Hello, Dolly! in the 70s and 90s and even 2017
A few different productions of My Fair Lady, King and I, and La Mancha that weren't carbon-copy revivals but were pretty damn close in the staging, design, and even casting.
The success of No, No Nanette in 1971 might have had something to do with people realizing that it's GOOD to reexamine an older show! (And something like Show Boat, which has never had two of the same production.)
