Manual (Standard) Models and Types
Although from my experiences all manual equipped V8 Monzas had Saginaw 4-speeds, I once read that Muncie made some so-called Saginaw style transmissions that were used in the V8 Monza. If anyone knows anything about this e-mail me.

Factory V8 Monza Bellhousing, GM part number 354496.
(pictures copyright Bob Gumm's "Building the V8 H-Body" website)
  Here you can see the factory V8 manual transmission bellhousing (GM p/n 354496). I've also discovered a second part number (GM p/n 360162) that looks identical to p/n 354496. Notice how driver's side of the bellhousing has one bolt hole missing! This was done for clearance purposes. Also, notice the clutch pivot ball hole is positioned at the upper right of the bellhousing. This again was done for clearance and because the clutch arm is cable operated. I suggest you use a scattershield bellhousing for performance applications. You will have to dent the firewall to trans tunnel area slightly to use a scattershield bellhousing.5-Speed Manual
Some H-Bodies had Borg-Warner T-50 5-speeds. If anyone has anything they would like to say about this transmission please e-mail me.![]()

3 Link (Torque Arm)![]()
The factory 3-Link Torque Arm Suspension was the best design by far. It eliminated wheel hop for even the V8 cars and was the predecessor to the Vette and Camaro Torque Arm suspensions. It attaches to a bracket attached to the rear housing of the transmission.
