How do you fit a sway bar on a eb4 s2 thunder tiger?

Rear sway bar kit has everything required except 2x 3mm bolts which screw into the front of the rear arms. The two ball joints screw together with the threaded bar supplied. Remove shocks and fit ball joints to lower arms with the ball joint with the grub screw uppermost and using 2 x 3mm screws which you will need to get from your local hobby shop. Slide the bar into the 2 ball joints and secure at the rear of the diff housing with 2 washers on the screws beside a small channell which is intended for the sway bar. Then make any adjustments and lock off the 2 grub screws on the upper ball joints. Replace shocks. Done!! Front still to do but will be the same and again requires 2 screws but slightly shorter.
