out of commission, cant drive my dart anymore

Since boots are new, I would try cleaning the grease off and gluing with crazy glue.
Don't laugh, this can work, especially if there's only one hole. There are probably other glues that would work since rubber is not ancient / thin. I'm late to this party but I always mark eccentrics and measure ride height frame to floor BEFORE taking anything apart.
That way you've got a starting point when putting the car back together, Glad you're tackling this!
