Steering on the cloumn shifter question

[Arky]

Hi, my shifter on the column is very slack/sloppy/loose. It seems that the shifter does not have the return action. Gear selection is fine but I fear that the shifter could "fall" into "reverse" on its own from "park". I have fixed the sloppy steering column by doing searches but I cannot seem to find any info on how to fix this. Could anybody here please point me in the right direction ? Thanks in advance. 85LWB/350/700r4
