jimshipp don't let all these #'s confuse you. You have been told correct w/ 6x8's / 5x7's fitting our vehicle's. The 6x8 & 5x7 size speakers will do the job because they fit. So if you haven't found the 6x8's go back out & look for 5x7's
Good luck & if you have any ?'s let me know & I'll gladly try
