![Huh](http://www.matrasport.dk/forum/Smileys/default/huh.gif)
.. I'll measure the thread incline tomorrow..
Well that 16mm diameter thread size is common to many Talbot engines, and when I got my adaptor all I said to the guy was it used a 16mm thread, and straight away he knew what adaptor to provide. If you want the pitch too I may be able to find out if I have a moment. I'll see if I can measure the thread sticking out of the block.
