I hope you may be able to help.
My ongoing trackday car has hit a stumbling block.My XR4x4 needed some negative camber on the front and therefore I bought some Adjustable TCA's with rose joints from TAS.Now,it looks like they've sent the wrong ones as these have a threaded "retainer" on the end that goes into the back of the hub/strut as opposed to a ball joint.The only thing that may get around this is a Cosworth brake conversion using the Cosworth 4x4 calipers and discs,but I am unsure as to whether the Cossie stuff will help.Any ideas ??
Also apart from the relevant owners clubs sites where's the best place to get used cosworth parts,are their any specialists out there ??

Many thanks for any help
