Here is a new dipstick tube in stainless steel for the DB5, DB6, and DBS engines.  These are commonly dented and unsightly so here you go. Complete with stainless steel steady bracket.  This is the way we go on the engines in our shop.  Beautifully made in the UK by JMB Services.

We have the larger version for the DB4 engines in our eBay store.

We are a stocking dealer for JMB products in the US.  JMB Services 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!
