Selling this Perma-cool oil cooler that I bought ages ago and never installed. It's all aluminum and includes 48 inches of hose, 4 hose clamps and 2 sheet metal screws for installation.
The cooler is 2-1/2" wide, 18-1/4" long (including the fittings), and 1" thick along the fins. The mounting holes are 15" center-to-center.
Summit Racing is selling similar units for about $70.
