What I did, because no one in the ABQ area had any spacers, was use a dremel to remove the basket material for the front speakers.
Once you have removed the basket material (they look like legs coming from the magnet to the mounting area) you can also remove the mounting lugs for the speaker leads.
This will leave you with a rough opening. I then filed down the remaining material to make it a smooth wide opening with as little obstruction for the new speaker as possible.
For the speaker mounting surface I used silicone (DONT PUT YOUR SPEAKERS IN YET PLEASE) to create a smooth bead all around the mounting surace. Let it dry completely. Drill your holes and drop in your new speaker. I dropped in some tantrums and they sound great, the factory spacing and the use of Dynamat lets the midbass out nicely... now all I need to do is get the tweeters out of the factory locations...they scream and the Xover has no attenuation circuit.
