Taking the restomod/custom route often means stock replacement parts (or even aftermarket upgrade-level parts for that matter) out of your favorite catalog just won't work in your build. Whether it's custom offset wheels, wiring, or even cooling system parts, sometimes the only answer is to work with a manufacturer's custom build division. While these parts sometimes cost a little more, you're guaranteed to open the box when it arrives and the part will drop right into your project.
Rusty Gillis of Gillis Performance Restorations is currently building a restomod '68 Mustang coupe with modern suspension, custom body modifications, and a 4.6L Two-Valve (aka an SOHC) fuel-injected modular V-8 under the hood. The modular engine's cooling system from the factory uses a cross-flow aluminum radiator with electric cooling fan. While you can find aluminum radiators for vintage Mustangs (and other Fords), many with optional electric cooling fans, there's nothing on the market that is a direct bolt-in for such an engine swap. What this means is that we have to look to an aftermarket custom solution. Enter Be Cool's Special Build Department.
The Special Build Department is Be Cool's optional service when you can't use one of the company's off-the-shelf part numbers. With more than 1,100 different part numbers, there's often a Be Cool radiator or module system that will work for a custom built car. In the event that none of those will work, the Special Build Department can jump in and take a standard part number and modify it accordingly, or it can build a complete custom radiator or cooling module from scratch to your build's requirements using the custom build order form.
This order form can be found on Be Cool's website and gives the department critical build information/measurements that you provide. Like any custom manufacturing process the end product is only as good as the information that's input into the system, so accurate measurements and fitting locations are paramount when you submit your custom build form. Turnaround time for a special build unit is 7 to 10 business days. Special Build Department engineers will discuss the provided build information with the owner and determine the best course of action and value for the customer. Sometimes this means using an existing direct-fit part number with modifications or they'll build completely from scratch. Currently, Be Cool offers direct-fit replacement radiators and cooling modules for '65-'73 Mustangs (and late-model Mustangs too), '55-'57 Thunderbirds, '60-'65 Falcons, '62-'69 Fairlanes, '57-'71 Galaxies, '68-'69 Torino, and most F-series trucks.
