Master/Slave Cylinder thread pitch/size?

[Bigfacedave]

Evening all, I have bought one of these master cylinders
LAND ROVER SERIES 3 CLUTCH MASTER CYLINDER on eBay (end time 16-Sep-10 16:02:27 BST)

and one of these slave cylinders
LAND ROVER DEFENDER CLUTCH SLAVE CYLINDER(ex 300 & TD5) on eBay (end time 16-Sep-10 17:01:19 BST)

I need a braided hose to go between the two, my problem is I dont know what size and pitch the thread should be? I have tried a couple of garages just to see if they have a fitting that will fit to work out what I need but no joy! Just wondering if anyone on here knows off hand what size and thread pitch I need! Thanks in advance

Dave.

old thread sizes I believe are 3/8 x24TPI UNF & 7/16 UNF new thread sizes M1O X1.0 & M12X1.0 two sizes used on tandem systems
