Sat. night I noticed that someone had tried to break into my Blazer buy busting the vent window but I guess my alarm scared them away. (best $300 I spent so far) It looks like they pryed a screw driver behind the glass and popped it, which is the easiest way to get in. I just wanted to know if its difficult to replace. I know LMC has em' for like $35. Do I just get new glass or do I have to get all the mounting peices also? Thanks for any help.
