Help... Tie Rod Ends Not Fitting

[drag-on silvia]

hi guys, so i stuffed my old set of tie rod ends trying to take them out (another story) and ordered a new set through fulcrum. they arrived and i wasnt paying a particular amount of attention and just threw them in, tightned the nut and didnt think anymore of it, though now i have gone for a wheel allignment and they showed me they could move the wheel without the red even moving, upon further inspection it appears they have supplied me with the wrong rod ends. the taper on the rod end is about 1-2mm to thin for the nuckle. this is where is gets weird, i went to pedders to see if they had any idea what the story was and their listing was the same as fulcrum. now i have thrown the old ones out so dont have anything to match up with.

my question is, are the gtst rod ends the same taper size as the gtr? or are fulcrum and pedders crazy and their a different size and have supplied me the wrong ones....
