I work for Evans cooling and we make custom radiators. We have never had a problem with any radiators to be made. Ours are also all aluminum being able to flow more coolant due to larger tubes than a copper brass one.
We have made them to fit very difficult situations and they always have fit perfectly when the customer gets it. We also do custom shrouds for the radiators we make along with fan mountings.
I just wanted to let people know there are other alternatives when it comes to having a custom made radiator, we don't shy away from any vehicle.
