Here is a complete kit of chrome cylinder head and cam cover nuts with washers for DB4, DB5, DB6, and DBS engines.  It is getting harder and more expensive to get things rechromed these days so this is the way we go in our shop.  Beautifully made in the UK by JMB Services.

We are a stocking dealer for JMB products in the US.  JMB manufacture a line of classic Aston parts in the UK.  Their products are innovative and improved versions of items like water pumps, oil pumps, breather tubes, engine studs, and various and sundry engine parts. 

Buyers outside of the U.S. please note; many countries, Great Britain in particular, have become very aggressive in collecting import duties and fees on items purchased abroad.  Please be aware of this as we obviously have no control over these policies and actions.
Ebay is also now collecting duty in advance on all international shipments.  The duty will vary according to country and will be based on the full selling price.  This is not under our control, so please be aware!
