I have read many have made changes by replacing the original FSJ box with box S10 98-04, with great satisfaction for road use.
It's an upgrade-swap that I would like to do along with the hydroboost for the brakes.
I read that combined with the S10 steering gear, another important point is the XJ 88/94 shaf drive.
I'm starting to collect the pieces first with what I can find here in Italy, before buying various parts from you in the States.
I found the drive shaft of an XJ 90.
I am writing to ask if changing and installing the steering gear of this XJ can give a significant change in behavior, or if this box has the same relation of the arts and behavior to that of the FSJ.
I could have it right away without taking a steering box for S10.
(my GW is a 89)
Thank you all
