98blacksr5

On my 98 4runner I have been having a vibration when I'm going 60mph so I checked the transmission mount and noticed that when I put a big screw driver in the mount it moves up and down allot. Also when driving over speed bumps the shifter will move forward and aft. At AUTOZONE they have a mount from Duralast for $12.99 and I was wondering If that was a too cheap of a part to go with? i don't want to replace it twice. My 4runner is a 98 SR5 V6 2WD 4runner with 127k miles. Thanks
