i wouldnt bother with trying to get it fixed.. it will prob rust again... it took me a year to hunt one down with no rust.. its almost impossible.. you could go onto ebay motors UK and look at the fibreglass ones from poland(about 50 pound i think).. or toyota still have them... 700 each and 150 for the seal.. Or go have a chat to some of the old school motor resto ppl.. ones that do alot of hot rod stuff.. they might be able to fabricate you one.
