Im hoping someone here can help me out. Im building a liquid cooled chopper and the factory raditor looks awful. What I want to do is replace it with somthing that looks good or can be concealed. To conceal it it needs to measure around 12x5. I have found many trans and oil coolers that would work for either plan but they all have tiny fittings. Are there any coolers that have fittings around 3/4s? All the chopper guys tell me to use a car heater core which might work for concealing it but there a know good sources for heater core measurements. So I figured street rods always have nice looking cooling systems and some street rod guys could help me out.
