Front Speaker install issue

[scottsubarus]

Son installing replacement front speakers SONEY EXPLODE 6.5 inch. into doors.

He said that someone has already replaced the factory speakers and the attached mounting bracket. The hole is too big for the SONY'S so was wondering what anyone else has done when presented with this kind of problem. Does anyone make an aftermarket spacer or bracket?

Am trying to find a pair of USED factory speakers to get the brackets off of them, but was checking all possibilities.
