Do the dry sump 6 speed Grand Sport radiators have trans or oil coolers built in? Looking to upgrade to a Dewitt's.

look at ether side of the radiator are there other then coolant hoses hooked up?

When I had my Dewitts installed, I was told I needed to buy an aftermarket trans cooler to replace the one from the radiator. (I installed just a radiator with no trans /diff coolers added in). I took it a step further and installed stand-alone trans and diff coolers with fans, since I track the car. I know our cars (M6 GSs) come with a tiny diff cooler, and I am pretty sure the trans cooler is routed through the radiator from the factory. I also know DeWitts sells radiators w/trans and/or diff coolers built in.
According to the Wiki page for our cars, they did come with Trans coolers: https://en.wikipedia.org/wiki/Chevro...6)#Grand_Sport
