19) Begin installation of the shift rails by mounting the bearing retainer housing
in a smooth-jaw clamp. Install two new springs (Fig.18) into each of the
two vertical bores in the housing. These springs, which can be purchased
as an option, are stiffer than stock therefore reducing the tendency of twin
stick arrangements to cause the tcase to pop out of gear while under load.

20) Place the original detent ball on top of the exposed spring in the left bore
(Fig.19). Begin this procedure on the left rail as shown. Position the proper
shift rail (Fig.19a) with the end-slot facing vertical. Push the rail up to the
detent ball.
