Chinook RV

I removed the door panels in my '99 to upgrade the speakers. Same concept but the "circles" (showing where to unfasten) are in slightly different places (I think the door panels changed when the dash did in 1997). Just so later folks know. I think I used a youtube speaker replacement video (was back in 2014).

OK, another project besides the MorRyde. The driver side regulator has some cheap plastic part that broke when I was rolling up the window, and it won't move up anymore. I took the inside panel apart, and I am now staring at the rivets that holding the windows to the metal bar on the regulator. Looks like I am looking at the OEM and nothing was touched on this side, but the rivets is going to be a pain. Looks like I will either need to punch out the mandrel, or drill the entire thing out, both steel mandrel and the aluminum rivet. I am kind of worry about shuttering the window if I punch it out. Anyone have any experience and tell me if I should DIY, or let my mechanics?
