My driveshaft for the T56 magnum transmission is a breeze when compared to the the V160 and its adapters and bolt flanges! This shaft installs in 5 minutes using the slip yoke on the back of the T56 magnum and then a universal or factory adapter on the rear side.
This driveshaft is available for the Supra TT AUTOMATIC rear and the Ford 9" rear. I do not offer the 6-speed rear flange because that 3.13 gearing is just too low of a ratio for the T56 gearing. The Supra driveshaft is a bit more expensive because it does require a bolt flange adapter on the rear flange.
I offer driveshafts in both aluminum and carbon fiber. The carbon fiber is a great option because its not only strong, but also allows flex which is really important when it comes to hard launches in a 6-speed application.
Note: I can get any shaft made using your dimensions and flanges. So if your swapping the T56 transmission into a different car feel free to let me know what your doing and I can get you a price.
