Odd thing about my '04 is it has the '03 filler tube. So it takes the '03 cap. My build date is, 11/03. The difference is 3 prong or 2 prong latch.
I took delivery in 6/04. I got left over parts...LOL
Plus it sure set for awhile before it was sold. Probably why my drive out price was $8.5k less than window sticker retail.
I always wondered if they would have took less. First time in my life, no haggle. I told them what I would pay. They imediatly said, OK..........
