Series 2 brake master cylinder fluid outlet to big

Just on with another restoration a 1968 series 2a station wagon lwb, just fitted a good bulkhead as the origanal one was a bit past it, anyway got new brake and clutch master cylinders, and fitted the brake master and found that the outlet pipe is to big for the unf tube nut for the brake line, The inlet from the resevoir with the larger diameter pipe is ok but the outlet is the same size as that, i have checked with paddocks and they say they have sent the right one and checked my old brake master and it is the same, so i have to find a tube nut with the same outside diameter as the inlet feed but with inside diameter of a normal brake pipe, any ide'as

Went to Paddocks today and they said they cannot get the adaptor for this job, wouldn't you think that if they are selling a replacement part they should make it so that you can use the origanal brake pipe ( with larger tube nut ) or if like me you have allready robbed this part for a previous resto you can get an adapter to connect the 3/16th unf tube nut straight in to the brake master

Have you tried your local hydrolic places ?

Just found a place on tinternet, Holden vintage and classics, they do one its a brass or steel 7/16 unf pipe nut for 3/16th pipe, cost £1.36
