P38 fan shroud

i have a 16 inch pacet fan directly mounted onto my rad, i want to fit it to a shroud then fit that to my rad, so it pulls air through the whole rad not just a 16 inch diameter bit in the middle!
any one know if there is a shroud out there to do this, or should i get busy with some sheet ally and tin snips??

Can't help directly, but it may be worth taking some measurements and checking out your local scrappy, from memory I think the 'Jeeps' had them fitted

that may be a good idea, do they fit onto a r/r rad i wonder, modification i bet wont be too hard but i need a 16" dia hole for the fan i have.
this is currently what i have, a bit silly as only half the rad is used when stationary or in traffic!!
