I have a gmk420 and the one from walmart (which my head unit doesn't even fit in) no mounting holes line up correctly because they don't reach all the way across (its too narrow) any one have this problem?

 

I bought 3 kits so far 1 Canadian Tire 2 from walmarts ..the only way my player works is hanging halfway out

I'll be replacing it soon with a double din unit and pay someguy to worry about it lol

 

After my Fourth try, I got the right kit from a car audio place.. In now finished, except my parking brake won't release now. It has been a nightmare
