Do all Cornelius kegs have the same size posts?

Well there's two different styles - ball-lock posts, and pin-lock posts. Other than that, the "size" of the posts are standardized.

It depends on what you're referring to as far as size.
-All posts will accept standard ball lock disconnects, obviously. Gas posts and liquid posts are slightly different and usually a gas QD will fit (tightly) on a liquid post, but a liquid QD will not fit on a gas post.
-Thread size of the post terminals varies based on keg manufacturer. Typically thread sizes on the same keg are different for gas posts than they are for liquid posts.
-Hex size at the base of the post varies based on keg manufacturer/model.
That side, most of the hex sizes on mine are 7/8" with some of the gas posts actually made by the Cornelius company having a 12 point star. I've seen some that are smaller, but I wouldn't be able to say for sure what size they are. I have a converted pin lock keg like this and I just use an adjustable wrench to remove those posts.

For ball locks, at least, the only thing that's "the same size" is the QD interface section. Otherwise, threads differ - not only from manufacturer to manufacturer, but line to line in some cases; heights differ - there must be at least a half dozen ball lock post heights extant; and finally the "hex" section differs - and sometimes aren't even hex but are 12-point...
Cheers!
I have some 7/8, some 11/16, and some that seem to be metric. Some have 12 pointed 'stars' on the gas "in" posts and that's a different wrench than all the others.
Out of maybe 2 dozen kegs, I have about 5-6 different sized ball lock posts. I have three deep sockets for those three most common, and then a 12 point wrench, and then a box wrench in the weird metric size.
