Interesting site that... some rare-ish bits on there. Need to be careful of anything that could be different between LHD and RHD. I see they have some steering knuckle boots for PAS cars though - might be worth a punt as a replacment for a non PAS one, although there are other ways around that problem - steering rack boot / driveshaft boots cut up / Old inner tube, etc.
