I need help with a 1997 eclipse gs front engine mount

Hi guys, I really need help with figuring out how to put the front passenger side engine mount back in the car. There just isn't enough room for the bolts. Getting it off required a lot of jerking and pulling and wiggling. I am repairing the car for my older brothers at my school. I've got 2 hours 28 minutes each day and I really would like to have the car done tomorrow which is realistic ish if it all goes smooth. I need some methods that don't require me drilling or cutting a hole I'm the car. The cat also had a 420a in it.

I tried posting in the eclipse subreddit but had absolutely so luck. Nobody replied which is odd because they all talk about the cars... Please guys advice is very much needed.
