I am trying to source what appears to be a very scarce part that goes on a 1984 37' Phoenix with DD 671-TI that were marinized by S&S (Stewart & Stevenson). Here are the details

Part: Intercooler
Manufacturer: Modine
Model No.: 5148353
Part No.: 1A13130
Original Part S/N: 05231

I am also trying to source the air inlet and outlet air horns for the intercooler. Should have some pics of the unit soon.

If anyone has ANY leads...I would greatly appreciate it....

Thanks!
