Rad for Duster /6 to 340 swap

Do you know anyone with an 80's 318 truck?
There all the same ubtil they went to the new body style.
The reason i ask is maybe you can just take some measurements of the radiator and measurements of your Duster before you buy one.

I never used a truck radiator in a car but this is what i would do if you can't find anyone to confirm your question. :)
