if i take off the rear emblems (tahoe and chevrolet) on a 04... will it have any holes on the panel?. or is it just 2way tape holding it on?....lmk...

Its just double sided tape. You should be able to pop them right off.

thanx euro, is it the same for the door moldings?... also any easy tricks to take off the double side tape...lmk...

I am not sure if it is the same thing as the mouldings. But a tip I can give you on taking off the emblems is by using a nylon string in removing the emblem. Worked for me.

Not sure about the door moldings. I don't own a Tahoe, but I'm pretty sure the same trick will work.

If there is any residue left from the emblems, rubbing alcohol worked pretty well for me.
