I wanted to replace the emblems or I should say front and rear badges with custom ones...
Any tips on this? As in, do I need to remove the old chrysler badges and how?

 

I just replaced my SRT6 badge on the back with the updated new one. I'm very pleased with the results. If you're thinking about replacing the Chrysler logo, Andrew has tons of pictures for all the options available. I still haven't decided what I'm going to do.

 

What I do is use a hair dryer to heat up the emblems and then carefully with dental floss slide it up and down from side to side. Then use some goo-b-gone, or if not handy then alcohol should do, and put on your new emblems. It has always worked wonders for me.

No need to remove them at all.
