[QUOTE="keep_hope_alive, post: 8862490, member: 576029"] Made a big push on Friday afternoon and worked till 3:30am on Saturday to have a completed Phase 1, ready to drive again! Treated the rear panels with CLD, closed up the speaker hole, and then covered them in Fibermat 45 [img]https://hosting.photobucket.com/images/e128/phat_funky_beats/20231103_174221.jpg[/img] [img]https://hosting.photobucket.com/images/e128/phat_funky_beats/20231103_175447.jpg[/img] I reinstalled all of the interior. No reason to show pics since it looks stock. No evidence of what I've done. I finally got to drive it for the first time since August 28th. Around town with some music on at a reasonable volume there is no exterior noise to distract you, it's really nice.
