VT Hydratrak

[Cashman_309]

Do the VT GTS Hydratraks come as an M80 or M78?
Is there a difference between VTI and VTII Hydratraks?
Did the VTII even have Hydratrak? I seem to get the feeling that it was something discontinued after VTI

I'm not buying one but I might be buying some gears that came out of one to put in an M80. M78 and M80 crown-wheels and pinions are not interchangeable, hence the reason for my questions.

Searching across many forums has yielded little info on the subject, unless of course it's cause I have been using the wrong keywords.

i am running a vt series 1 hydratrak in my vs, dont think they were continued in the series 2, might be wrong.

i know the VT SI diff has a 4 bolt flange and the VT SII has a 3 bolt with donut rubber flange. not 100% sure on the M78 or M80 so i wont comment.
