Flipped Radiator shroud

Yup, it can work- for similar sized radiators, of course; and not in all cases, kind of depends on which /6 shroud you're starting with and which radiator you've got. A bit of a crapshoot. Some trimming may be required depending on which inlet/outlet positioning you have, and possible clearancing for the trans cooler fittings & lines. Nothing major. Definitely worth a try if you've already got the parts lying around, definitely cheaper than buying a repro.
