used to centre pop the gear linkage on these before removal,sorry cant remember the adjusting method,think there is a pin for the bottom of the gear lever assy under the veh but cant remember the g/box end position,dont think you should hear the pedal ratcheting,once it is adjusted that is it,it will adjust gradually with wear,if you can get your linkage sorted out maybe that will help matters,try your library for a manual for a quick look at adjustment method
