This clearly illustrates the drawback of metrication. When this innocent little bush was invented at Abingdon, it was meant to be 1/2" tall. Paul now tells us that it should be 145 mm - obviously a slip of the finger, and now Ian corrects that to 14.5 mm. But 1/2" is in fact 12.7mm ! I am no engineer, but in engineering terms, the difference between 14.5 mm and 12.7mm is enormous.
Bring back the pound, say I.

hi,
The two blocks that I removed from my 4 seater PA 1232 measure 13.9 & 14,5, discrepancy has undoubtedly come from 70+ years of wear.

I have just been into the workshop and dug out these, which I thought were going to be the hood fixings you are all talking about, however they appear to be nothing like the other picture or drawing. Any ideas what they are?

Jonathan,
I think they are sidescreen fittings.

Fred is correct, they are side screen fittings.
