You could have saved yourself $117.00 if you would have skipped the transmission crossmember and rear transmission mount as they are not needed for your application. In fact, you may want to consider removing the transmission mount from the transmission and let the transmission be supported by only the front mount and the bellhousing mounts.
Why? Supporting the engine/transmission at 3 points can cause serious problems. It has been described to me that it is like holding a stick at the ends with each hand and putting your knee in the middle. The stick is easily broken.
If you are concerned about the T5 transmission hanging out unsupported behind the bellhousing, worry not, as these trucks which came with SM420 4 speed transmissions hung out unsupported behind the bellhousing. That transmission will give you a hernia to lift it up off the ground.
