Those standard split pins are very weak compared to coiled pins. Spirol (and others) also have a heavy duty version you may want to look at for additional strength and avoid pin breakage. For example, the standard 5/16" Spirol pin has a Minimum Double Shear Strength of 5,500 lbs, while the same size heavy duty pin is rated for 7,800 lbs. I suspect both of those are considerably higher than standard split pins.

That 5th/reverse rail internal is the largest of the 4 rails.

All 3 top rails are 5th/reverse, 3/4, 1/2.

The 5th/reverse internal rail is driven by an intermediate linkage lever.

I find it difficult to believe that rail could snap it half.

Any photos?

Where in this transmission are the shift linkage stops?

In other words, if I bang the shifter hard enough will a positive stop be there to stop me breaking selector forks etc?
