Use bmw 5 series track rod ends. That is what I am using, and they are the perfect taper for the mx5 hub. Try and get ones for a saloon around 1995. If you like I can dig out the part number ? Eurocarpats.com are really cheap for them, just type in 2l petrol and they will pop up. I bought mine when they had a sale on, which they have frequently, and they were 2 for £11 delivered. Keep in mind that if you do use them, the threaded insert in your front top wishbones have to be tapped out to m14 x 1.5
