Depends on what you mean by SS Monte front end. If you're looking for the look of the MC SS that some elkys have, that's a choo choo nose (front bumper). Not the same as the monte although it looks the same. The monte bumper won't fit elky fenders. You could put the entire monte front clip onn the elky. Fenders, bumper, hood and core support will bolt on. But you'd need Monte doors with the elky glass installed in them. At this point you'll have different body lines on the 1/4's and doors so either rework the lines on the 1/4's or rework the doors with a fade out to the elky lines.
Or just get a choo-choo front bumper and components and be done with it. Try Honest charlie's or Lauren Engineering.
