Wanted Ktm 500 exc radiators

[171steve]

Hi guys im busy rebuilding my 500 and the radiators are bend and used up more than i wanted them to be so i need a new set.
Are there any aftermarket ones cheaper than stock available or can they be repaired
Any advice would be appreciated
Will any of the other 4stroke exc models radiators fit?
