replacement non exspansion vesal radiator

Hi everyone i have just completed a 1.3 engine swap and found my original radiator is broke. i went to numerous parts suppliers to get a rad with inbuilt side tank but nothing. they only have later exspansion vesal versions. Any ally or options i could try that will fit?
