The Treble 'r' Problem!

[toerant1]

I have a 1990 Carina 2 and both roof rails are rusted through at the ends. I have taken them off and think that they are beyond repair . I took them off thinking perhaps that the rust moth could extend to other parts of the roof? I could leave it as it is without fitting rails because the channels underneath are part of the metal roof and secure, it just wont look as nice with shiny roof rails there?

Has anyone any ideas where I can find replacement rails or what other steps I can take to deal with the situation ? Are the rails on my car the same as on any other Toyota models for example? Or is it just a matter of putting up with a less than complete car rather that paying out a third of its value on visiting a Toyota dealer and having new ones fitted?
