So I purchased a arrowhead decal on Ebay, and when I got it it seemed a little big. I still applied it and it looks like crap because some edges ripped off and there are lots of bubbles. So please vote in the poll that would seem like a good size for my back window. I am going to get a new one regardless of what anyone thinks, so please don't tell me I shouldn't.

Here is my current one

what are the dimensions of that one? so i can picture the other sizes better..
is that a GPS module on the rear deck?

15in x 27in

umm, id probably go with the smaller of the two. but id definitely measure and maybe make a template or something to make sure you like the size.
