I've a 97 lude H22a.
Because my car is without ATTS and 4WS.
Is it possible to install a ATTS unit?
Or Should I just install a "normal" LSD
And is it possible to add 4WS as well?
Thank you 
Possible to do all of the above? Yes.
Is it worth it? No. (Just my opinion)
Possible to add 4WS? Yes.
Finding parts for your 4WS conversion in the U.S.? Good luck. :chuckles:
