Compatibility of replacement parts?

[Dalamar]

I just ordered FRU No.: 46L6329 which is listed as '14.1" LCD Bezel (for W/W)'. I'm going to assume, and please correct me if I'm wrong, that 'W/W' stands for 'with wireless'. Yes?

At some point I'd also like to order the 'LCD Rear Cover Assembly for 13.3"/14.1"', however, there are two separate FRU's for this part, one listed as 'W/W', the other 'W/O W' (without wireless?).

Now, after all that, my question is: does it make any difference which I order? Or are the changes significant enough that I can only order the W/W version?

I love my baby R31, btw, she's heaps better than the crappy Toshiba Satellite A-something I'm typing this on.
