When I posted the color parts on the first page, I wasn't being specific. Just generally saying, Pro LX/DX and MX3 have the charcoal or black interior pieces. Also, although the Pro DX did not have the charcoal interior, they did have some black pieces that the LX will not have, so, keep your eyes out for the DX as well for those things. The only all black interior swap parts are found in the MX3, that's true, but those are hard to come by in good shape, so for the average guy just wanting to mix it up a bit, the Pro parts are more plentiful and a more direct swap. Again, a hellava lot better than painting. I'll look into the mx6/626 (should be the same, right?) HVAC controls next time I'm at the JY. Problem is, I already have my Pro/MX3 controls and I think I've found a good switch in another car for the various other uses (a/c, defrost, etc). btw, anyone who knows me, knows that it takes me forever to get my projects done. I just don't have the time to decicate to this stuff, too many other things going on in my life. But, I'm trying to get them moving along, a step in the right direction will be if someone buys my 79 Z28 soon. Any takers? Good luck, Bill.
