@lhu1281 kindly pointed me In the direction of a chap that has started making type 4 alternator brackets in Canada, I've just bought one over and the quality was very good. It wasnt cheap at £43 including shipping but if I order 10 more I will get a small discount so I can get them here and shipped out for around 35 Please let me know who might be interested
Nice, however the brackets are different depending in age and type of heat exchangers. Just a heads up!!
