I have a 95 4-door S10 Blazer
My rearview mirror fell off about 2 weeks after I got my system.. The button fell off with it.. I went to Freds bought some glue stuff, and its been on ever since! My rearview mirror bounces on higher notes, my overhead panel (with temperature, garage door opener holder, and those little compartments) has developed some major rattle (tried fixing it but cant really figure out exactly where the rattle is?), both my side view mirrors bounce, my roof has a fair amount of flex on low notes (Late Night Tip to show off my flexing), the latch where my doors close rattle on the high notes, and my rear hatch rattles pretty badly on the high notes.. The rear hatch rattle isnt so bad on the lower notes.. Also get some back glass flexing and hatch flexing.. When I am driving without music I noticed more rattles and my back glass now squeaks..
But hell, Its all worth it!
