Does anyone know where I can get some 90 Spec MK4 Escort XR3i rear tierod bolts? The ones that bolt the end of the rod to the chassis? The nut was rounded off and required cutting to remove and now Ford inform me that the bolts are no longer available. I found a place on eBay which had them but the ones that arrived are too thin. I've also exhausted my mates miscellaneous MK3/MK4 bolt box without success.

Any ideas other than a breakers?
