1) Mounts are TORQUE mounts, inbolt them from the motor and unbolt them from the chassis.

2) Welcome to what we in the industry call the "***** pin". You need a 8mm punch and a happer. you hammer the pin out from the bottom, you MUST MAKE SURE WHATEVER YOU USE TO HIT THE PIN OUT DOESNT GO INSIDE OF IT. the pin will expand and almost become impossible to get out.

Make sure whatever you use it doesnt go inside the pin.

good luck
