Speaker Mounts?

[ToyotaHank1980]

I have a 1994 toyota pickup w/extended cab. I replaced the front speakers (4") with brand new infinity speakers with tweeters mounted on center. The issue I have is the tweeters stick out just a tad to far and just barely touch the factory plastic grilles when installed, therefore causing a very slight buzz which makes it almost sound like the speakers are slightly blown. This drives me nuts. Can anyone relate to my issue and tell me a solution? I swear I've seen somewhere a thing about speaker mounts or brackets but am having trouble relocating the site again. Can someone give me some advice? Thanks!

I hate to say it, but maybe new speakers... I installed 4'' 3 ways that fit perfect, they are pioneers...

just space them back with a small washer or 2 between the speaker and the factory grille.
