Curtain for dual core radiator?

I’ve been dealing with a slight challenge trying to find a solution to mounting a curtain to a dual core radiator, the issue being the attachment “ears” on the curtain aren’t long enough to allow it to reach the mounting points on the radiator that extend back behind where the radiator mount attaches. My current option is to weld (matching material) extensions onto the curtain frame & drill where needed to achieve the necessary clearance, which I do think will work, but I thought to put this up for feedback before I commit to it.

Has anyone else ever dealt with a similar issue? Is there even a dual core radiator-compatible curtain available on the market?
