WJ Overhead console (shell) with Sunroof into XJ

I've had a 99 XJ OHC for a while and was getting around to fixing it and installing it. The thing was fairly mangled and dirty, so I was in the process of cleaning it etc. when I was at the local PNP and saw the little OHC out of a WJ clunker. For $13 I figured I'd grab it. Took it home and put the XJ OHC module into the WJ's shell and now I'm looking at it and liking it a lot. The only thing is that the little OHC doesn't dip down deep and so the innards stick out about 1/2" or so...do we have that much room between our headliner and the roof?

Do you have a picture? I've had 3 wjs and just got an xj
..so for nostalgic purposes I've thought this would be pretty does it mount clean though I dont want gaps
