thats a rash and temporary fix, the metal has worn, stretched and fatiqued (sp) in the hinge and pin. trust me, you need hinges. im a mechanic i know what im talking about.
the multispline bits come in a socket set, mine are snap on but any cheap brand will do. i.e draper, kamasa, rolson etc.. i cant remember how much the two hinges cost mate it was done as soon as i bought my car and didnt keep a receipt. possibly rear 5 door hinges will fit, they look the same but the dimensions would need to be checked. try ebay you should get them there mate, dont buy them main dealer if you dont want to be ripped off
