We supply the 3J Plate LSD.
A 1988 model wouldn't have power steering, we would recommend a road spec LSD in this case
There would be additional torque steer from a plate LSD due to the lack of power steering.
A Quaife (which we don't sell) is the non-torque steer option.
The price is $1300 delivered.
I was directed to you by PeterT as the man to ask about a 205 LSD. I'm chasing one for an '88 GTI 1.9 - do you supple a quaife or a kaaz or something similar?
