Long DZUS fasteners - where to get imperial ones ?

[moglite]

These beauties hold down the cover for the fuel tank in my Morris Oxford Traveller



I need 4, and I'd like to get a matching set

Anyone know where to buy old/long/imperial dzus fasteners from

Diameter looks to be 3/8"

Not entirely sure how the length is measured.

Any help appreciated.

This lot any good? They don't list individual sizes on their web site: www.tridentracing.co.uk/racing-supplies/quick-release-fasteners.php#

Thanks guys - the RHF link looks promising, the spec sheets aren't the easiest things in the world to read, but I'll sit down in a quiet corner and get it done :-)
