I'm looking to install a Borg-Warner T5 in my '73. From the different comments I've read, the rear transmission cross-member for the change seems to cause a lot of heartburn due to differences in mounting point locations on the two transmissions. This transmission came from an '83. In '83 both the Nissan 5 speed and the Borg-Warner T5 were options. That being the case, were there different rear cross-members for the Nissan 5 speed and the T5? If so, why won't the T5 cross-member work? Or, were the body mounting points in different locations?
