Question about TR4 TR5 TR6 Water Heater Valve

[some bloke]

Hi all, I have an older Aussie assembled car here in the UK, and need a new cable operated heater valve. Exact replacements from Oz are stupidly expensive, but I have found this listing for a TR4 TR5 TR6 Water Heater Valve on ebay that looks like it might work:



Does anyone know what the thread diameter/pitch is on this?

Thanks for the replies guys - I eventually found a supplier who was very helpful and posted the exact one I needed. I will install it this week.
