I am not familiar with that particular vehicle, but I do not remember ever seeing a 4x6 gm speaker location that looked like there was room for a 5.25.

Im with i am an idiot on this one. Its usually 6x9s that are big enough to plate to put 5 1/4s in. You can just measure the hole and if it is large enough you can make a plate out of 1/4 Masonite or similar material and cut you 5 1/4 whole in it to secure to the factory opening. In My Navigator it cam stock with 5x8s up front but because the mounting bracket and whole were so big is was able to mount 6 1/2s up front with a custom made Masonite plate and removing the factory plastic mount for the 5x8s.
