I just called both places (Atlanta Exchange and Tri-city). With both you get the same bumper back. Both said about 3 weeks as of today, but that might change with the nicer weather. Tri was $300 and Atlanta was $275.
Don't know if you're planning on going to Spring Carlisle. Tri-Cities was there last year. I dropped my front bumper with them and bought an exchange rear bumper from them last year to save shipping costs. Don't know if they attend the All Ford show too but wouldn't be surprised if they did.
WOW! Will definitely be sending my set of smalls to them. I had no idea..... Glad I didn't throw any out.
