I sure would like to meet that MOM
The rear & front glass being removed will give you better results. My first attempt on mine was with the rear glass removed and the front in. I liked the finished product but then the forward glue started to release a little and then it loosened up
My words of wisdom is if you are going to leave the front glass in use GOOD glue, the stuff I used was this black adhesive that I got with the headliner. I won't make that mistake again, next time that good old yellow adhesive.
