So I got my stereo hooked up finally and when I turned it on I thought, well that sounds like garbage. Once I popped off the speaker grills in the front I realized why.
Anyone have a clever idea to fix this? It looks like they cut out the areas for the screws to hold in the stock 4x10's.
Thanks in advance.

Based on the pictures you are going to need to use an adapter plate to mount a better style speaker. Making one should not be all that hard. I have one setup to run my component speakers in the stock front location.
To bad the prior owner/owners decided to hack that are up for you.

As an alternative to the adapter panels that mount from above, you can use some simple sheet metal and make a plate that mounts from the bottom. Then you can use some window foam the close the gap around the speaker.

I replaced my stock 4x10's with Pioneer TS-A4103 4 x 10 2-way speakers in each of my GT's. They work pretty well with the Pontiac Monsoon radio that's installed. Probably would do better with an aftermarket aux. amp. Complete connect up, drop-n, screw down and cover up with the stock grills.

Whether you're staying with the 4" or going to a 4x10 or whatever, I'd do a patch panel underneath with the appropriate holes. Rather than sheet metal (prone to rattling, tinny, bad for sound IMO) I'd use a sheet of plastic. Due to my various projects I'm on a first-name basis with the local plastic place, but you oughta have a cut-to-size place local to you. (If not, https://www.tapplastics.com/ ships! ) I'd think an appropriately sized piece of, say, 3/16" or 1/4" ABS or styrene would do nicely. I'd prefer that over acyrlic as that stuff is harder to work with and more brittle. Measure and mark carefully and then go to town with your Dremel.
Hell, in a pinch you could do like 1/4" hardwood plywood from the Home Despot cut up with a jigsaw. I'd also just glue the boogers in, Liquid Nails or Gorilla Glue. I know it sounds totally hack, but again, you want something that won't come loose and rattle the way a screw or bolt can. Especially if you're going to 4x10's, there should be enough room to clamp it well.
As shown with the metal one, I'd install it on the bottom side as opposed to the top. It is painful to get to, especially the driver's side, but the grilles are a tight fit enough up top without moving the speakers up any farther.
This is the joys of buying old cars; you often wish you had a "previous owner seeking missile."

Thank you very much all for the suggestions. I will have to tinker with the various ideas and figure out what will work. I just discovered they tried to replace the rear speakers in the pillar by breaking off the grills and not removing the trim. Have to give them credit though, they actually managed to get those in with zip ties and not cut anything. Haha. The joys of a 35 year old car.

Well, since its already cut up might as well install some 6X9s. I put 6x9s in mine, but couldn't get myself to cut the dash since it was immaculate. Part of the dash blocks the speaker of course, but still sounds better than the 4x10s anyway.
With yours already being cut, you could get the full potential of a 6X9 install.

I've got Memphis Audio 6x9's in the dash of my Formula.
No sub needed.

If you have a 3D printer you can find the pattern on Thingyverse and modify it for your own app. I modified it to print out a speaker adaptor for 2, 3.5's. one is a tweeter, the other mid range.
