Xcessive Toyota Urethane Trans Mount - Series 1. If your looking to tighten up that tail shaft on your early style Toyota R154 or W5x transmission, this is what you want. We've made these Urethane transmission mounts to fit on the factory four bolt mounting top and bottom and added some adjustment by slotting the base plate to help with all of the swap guys.
We use our 75A urethane bushings in one of our aluminum castings with a double cross pin design for as much support as we can get, this is a huge gain in rigidity over stock rubber mounts. We also offer 60A bushings if you feel the standard 75A bushings will be to firm. If you have stock rubber motor mounts on the motor, we recommend the 60A bushings.
This Urethane transmission mount fits the factory 4 bolt pattern typical to early style R and W transmissions, i.e. MK3 Supra.
The base has four 8mm bolts on a 1.45" x 2.25" rectangle pattern (37mm x 57mm). The mounts are also commonly identified by the 2 bolts that hold mount to the transmission in a side by side configuration (See pics).
