Is this possible without using a SuperTop? Is there some RAT with rounded corners for a YJ? Thanks for any help.

There are ways to do it without going with a Bestop Supertop. You could use a Bestop Sunrider, or an aftermarket top made by another company. However, you will not find a RAT that has round corners because the RAT reuses the factory top hardware and the factory hardware includes the square corner"doorjamb". You will need an aftermarket top that comes with new hardware made specifically for the full hard doors. Sorry.

I thought for sure I had seen people running full doors on YJ's with factory soft tops, guess not. I don't really want to go the Supertop route. Thanks for the help.

There were 2 factory soft tops. One with half hard doors and square soft uppers and one with full hard doors.
