Hi all,

Would anyone know where (if possible) I could obtain the above with a larger taper to suit a different hub assembly? Possibly from another car

I have made queries, spent a couple of hours searching and browsing to no avail

Of course replacement OEM are plentiful and adj types, and as it is a Street car cant use a sleeve etc over the top,

Cheers

Tricky one this and something i briefly looked at a while back.
You can buy ball joints with tapered stud, however your problem will be adapting or finding one to suit a standard escort tca.

There are a number of places in the US that do them.. as they do them for muscle cars etc.

Good luck!

Cheers for that mate, would not have considered that type, gives me something to work with
 
Have to check if it can be engineered, otherwise will have to pay the dollars for the custom kits
