I never heard of anyone mixing them.
Not that simple. This should help:


The mag case 911 gearboxes (which includes the 1969 type 901s) use the same differential as the 914. The very early 915 gearboxes also use that same differential.

If one were to acquire a factory ZF LSD for the 911/914 be sure to get the proper LSD stub axles flanges to go with it. The length is greater and the open diff flanges will be too short. Our LSD or TBD does not require LSD flanges. You can use the stock open differential flanges with our units.

Kind Regards,
