The '216' mounts / 'rest'
If that engineer trait whats to use that shiny new bellhousing,the angle mounts will require the same specs to mount to frame. Modification has never been a challenge to this old wrench. I hear ya.
As I recall, the transmission does infact position on the cross member, however the mounting is shy of the original mount spacing on the bellhousing. Letting the bell mounts ride free will permit torque to load at the transmission mount. Good luck with your study.
