Both where a PITA, but i think i would have to agree about the pass side cause of the heater box.

best thing i figured out was take one side of engine mount off the jack it up a tad and it will make room and repeat for the other side.

 

Yep jack the motor up and drop the bolts out of the kmember. After doing that they went right in, no problems. Wish I would have done that from the start like I thought about doing, would have saved me about 10hrs and a sore throat
