Windscreen wiper blades rusty nuts - Replacement

[Arapo]

I bet I am not the only one whose windscreen wiper blades nuts (the ones that hold the base of the wipers on the scuttle panel..) have gone rusty. Has anyone replaced these? Wondering how easy it would be to do it myself, and if you know where to source 2 new nuts and what the dimensions are? I could probably measure it and find a supplier on Google, but if anyone knows, it will be very helpful!

See the photos. Any suggestions welcome.

Wow, even to replace a nut on a TVR seems to be a science! And I am so glad that you guys are on top of your thread measurements. I do feel bad for not being able to help more, considering I raised the subject, but happy to buy beers for everyone when we get to the bottom of this!!

They fitted the thread Ok, the thread needed paint removing and oiling ... so 3/4 UNEF 20tpi. The nuts are 10mm thick which is probably twice as think as the mild steel original ones ,but I think will fit... only tried them on my spare linkage not on the car.



UPDATE !!! Spoke to a lovely guy at Motalia and he's got another nut available 0.25" thick and 1.01" across the flanges and he's going to machine some stainless washer to fit nicely, which will make a much more professional job.

Perfect! Can you share details? How can we get hold of a set??

OK, let me know. Good idea about the penetrating oil..

The chap has done these as a special for me £40 / pair... If enough people agreed to purchase maybe able to get a bit discount on a group buy. He needs sufficient quantities to setup his CNC machines, I know he didn't have many nuts left and the washers were bespoke. They should fit all TVRs with the Matador linkage so that means all T Cars (Tuscans,T350,Tamora,Sagaris etc.) not sure about Cerberas .

Look amazing.. Count me in for a pair!
