VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1916-1922 - Model 490 490 gear shift pin

I'm weeks away from re-assembly, wondering what part H-334 the pivot dowel would be made of? This is the pin through the top of the tranny case that keeps the shift lever from wobbling around. It was missing, there is no threads that I can see, I'm hesitant to drive a steel roll pin in the hole as I don't want to break the case. Thinking about cutting a nail and using locktite so it won't fall out, any suggestions would be welcome.

FYI I did use a steel roll pin, carefully tapped into place and seems to work fine.
