Grill and Light assembly

[youngoldschool]

I'm possibly thinking about changing my 64 grill over to the 65 with the clean grill and go with the clamshells. Has anybody done this before and how difficult of a project would I be getting myself into. I have always like the 65 look, but as most of you know they are hard to find in good condition, that and when I found my 64 I couldn't pass on it because it was so clean. Any input would be much appreciated.
