That is correct for both sets of mirrors. I have 1989 hard doors on my 93 YJ with hardtop and opted out for the newer style mirrors because of the different hinges (also because I didn't feel like doing any more body work to the doors before I shot them to the existing holes from the small mirrors...just put new small mirrors back on).
The CJ style will also have to be drilled and tapped to do it correctly in the windshield frame, at least for the pic I posted above for THAT style of mirror. There is another set that uses other holes on the actual windshield hinge itself. Those would be the ideal setup. Sorry for the confusion....
