Big bolt at tail end of transmission
 

I've made a post on rx7club about this same issue but I was hoping someone here maybe had or could get the dimensions or more info of this bolt that goes at the shifter end of the trans. A user j9fd3s was helpful in pointing out the part numbers of these missing parts and it turns out some of them I can probably get from Mazda themselves. The only one NLA is the bolt itself.

If anyone could get me the thread pitch/size/dimensions of this bolt I would be very grateful since I believe this mechanism missing is affecting the positioning of the shifter block.
