I have replaced three of the four engine/trans mounts.Passenger top (under air box) Front lower center and real lower center.
I have a forth from Rock Auto but do not see where it goes.
I'd appreciate an assist.
Thank you.

Pretty sure it is on the drivers side and the transmission hangs from it just like the engine does on the passenger side. The two lower mounts control the torque twist and the two upper mounts hold the engine and transmission in the car.

 

Thank you!
I'll have a look shortly.
Regards,
Eric
