I really appreciate your swift reply!
(1) It's a bummer on the AC compressor. I'm half way thinking of just completely replacing all the AC components.
(2) I have searched so many auto-parts store and some clips that look promising, fail.
(3) Thanks for the speaker sizes, I think the front ones are 6.5. The rear ones, now I know, are 4.5. Much appreciated!
(4) & (5) Just submitted the request for invite.
(6) I've seen a rather large truck-mods(lifting being the popular one) establishment nearby, i'll definitely hit them up.
So for now, most of them I have an Idea of where to go. I'm down to the AC compressor and the panel clips.
