I am working on installing my new grubee skyfire and i cannot seem to get any of the motor mount studs off no matter what i do. I have found a lot of threads on the poor quality of the stock ones so now i know to upgrade them but i cant get a single one off. I tried needle noes and regular pliers, wrapped a towel around the studs and tried, and wrapped a rubber band around the studs and still got nothing. It seems like it is easy for everyone else so i wanted to see if you had any other tips. Thanks - great forum by the way, i'm learning a lot
