i holed my left radiator...... and have tried to tig it up. but without taking the inside bracket off to get full access to the core it's just not sealing up.. there aren't many after market radiators that i can find here in Aus. for the old LC4, i don't know if radiators off other models like the 525 etc. there are a few different brands/ manufacturers of after market radiators, but none seem to list them for the 640. the ones listed for 03-06 400-525 don't look like the right pipe outlets etc. for 02 640... any info is greatly appreciated.
