Rough in distance for old Kohler Rialto?

I have to replace one this weekend and need to buy the replacement first. Does anyone recall the rough in for the old (1970's) super quiet, one piece Rialto toilets from Kohler. Standard 12"? Or something oddball?|||The standard rough-in is 12" but can be 10" 0r 14". To check the existing without removing it, measure from the wall to the center of the closet bolts. Allow for the thickness of sheetrock,tile and baseboard as rough-in is measured from the studs.|||Sorry Bob, It is measured from FINISHED wall, that makes it 12 1/2" from the studs if 1/2" drywall is used. 40 yrs huh?

|||12" is standard as for as long as I can remember. From finished wall surface that is, but if you are off up to an inch either way, you SHOULD be fine (not totally fine for certain)
