I may have the cutout dimensions's been years...

Here is one difference between the cutouts for the RB and EB tops:

The RB cutout starts right behind the B pillar support that spans across the fact the rear spot welded flange of that support needs to be removed as the rear vertical face of the roof support at the B pillar is the front edge of the cutout.

On the EB, Sportsmobile installs another B pillar roof support directly behind the existing support and the cutout starts behind the second support. I think the support that they install is one harvested from further down the roof when making the cutout.

Since you are installing an EB top on an RB you'll have to determine where the cutout starts fore/aft, but I can't imagine it will be like the EB case above.

I would suggest sending AndrewST a PM and see if he can give you cutout info, since he did exactly what you want to do.

Also, do a search here for my build thread called "popping my top"......that should have some relevant tid-bits as well.
