i need a rear subframe cause mine has corroded totally. i was removing my swingarms when i had to convince a bolt with a hammer, and after giving the bolt a few knocks. I saw that the "tube" connecting the sides of the subframe had a crack in it and when i touched it it just fell in to pieces! i can put my fingers in to it and the crack gor almost from one side to the other totally corroded. so where can i find a new subframe without getting totally ripped off by original fiat parts? been looking on ebay but i can only find used complete axels so far, and i can find one in scrapwards in Sweden. Can i use the subframe from some other Fiat maybe easyer to find?
