Rb head oil drain dimensions
Hi all,
I've been looking at buying a rear head oil drain kit for my 25/30 such as the one spool or Franklin engineering make.
However I work in a machine shop and could easily make such a drain myself, I was wondering however if anyone had one lying around they could take some measurements off (preferably vernier)
Mainly chasing total width, length of drain spigot, diameter of drain spigot, the dimensions of the oil ring groove, pcd of bolt holes. If anyone has the dimensions I'd be happy to make extras at a fraction of the cost! Thanks
