It's made by northern, I have one in my car. Same fittings, blue anodized filler neck, 3 dimples on the passenger side. It fits good in my serp belt camaro, not many real mods needed, works great, built well, I did a post on it a while back called "Northern Aluminum radiator=The sheezy" it'll come up with more detailed info and a lot more people's claims. Should still be within the first 5 pages on this section.

Re: New Summit Direct Fit Aluminum Radiator
So i got one question. It says it fits automatic trannys becuase of the built in cooler. Would it work in a manual car without those hooked up. or possible us those hook ups as a oil cooler or something? Just curious.

Re: New Summit Direct Fit Aluminum Radiator
You can use it without using the trans cooler. You may want to install 2 plugs to keep the interior of the cooler clean in case you need it at a later time. Not sure about using it for an oil cooler, I think the fittings at the radiator may be too small and restrict the oil flow. The radiators should be available for manual trans/no cooler and probably some cheaper.
