you will have to describe your fault more clearly,what bolt is `snipped` and what do you mean by snipped.Is it the pinch bolt on the gear linkage which is sheared?Is the selector shaft which goes down from the top of the g/box housing moving ok?There is a needle roller bearing just under the oil seal on that shaft which seizes,liberal oiling and some release agent are usually ok to get it freed off and keep lubricating through the year.
