For a Merc 470 (3.7 Liter) around 1987. The heat exchanger measures 4" X 27" and a fraction. Does anyone know of a good source or have one. Couple on ebay but one of them doesn't look right.

Thanks

Thanks for the replies. I am sorry I took so long to acknowledge them. I was able to find the heat exchanger locally.
