I think it depends on the availability of the part. I recently ordered one of the rear license plate lights because mine fell off and I got it in less than a week. If it's something that is in stock it will be fast, give them a call and I'm sure they'll help you out.
Make sure you order the correct ones for your wheels. The #05 is for the early '05 rear wheel with the protruding cap and #05a is the flush cap that fits all years of front wheels and late '05 to current rear wheels.
