A few updates:
I was able to get the holes cut in the door panels for the new speakers.
I used a two-part epoxy to attach the plastic speaker bracket to the door panels, and it worked great.
I also replaced the inner grab handle, as the one originally on the door panel was in horrible condition.
I also purchased a red start/stop button from Bimland Performance
Last week while I was poking around under the hood I saw the radiator was cracked so...
I will also be doing the oil filter housing gaskets at the same time (they just started leaking a few weeks ago)
