In the first post (If you read it yet again) you will note that I had purchased the accessory part 'Illuminated Sill Plates'. These generally cost just over $200 new from the dealer (prices may vary).

I happened to get mine from a forum member who had decided not to install their set.

You MUST have these to begin the 'mod' of this accessory. If you do not, the original sill plates on the Crossfire (SRT6 has them too) will only have a stamped lettered 'Crossfire' on it and not the cut out like the illuminated sill plates.

A conversion of the stock ones could be done, but it would probably require the use of a CNC mill to or CNC laser engraver type machine to cut out your letters where they are stamped now and this would be very expensive, probably more than the accessory kit itself.

Cheers!
