Get solid mounts. You need a motor mount and trans mount
You have a transmission mount (driver side) and a motor mount (passenger side). Then you have your upper dog bone mounts. Probably don't need to mess with those. So you sir need a total of two mounts.
As for the transmission mount and motor mount, just shop around, brand doesn't matter a whole lot with those. BUT if you do order solid ones, shake them and listen to them. Some of the "solid mounts" still come hydraulic. Try rockauto that's where I bought mine, and you can get a 5% off which usually pays to ship them.
Or just get poly for the square mounts..
