Looking for a pic of it. I bought one from an 80' Rabbit and it might be too large.
On the other Ferrari chat site, www*****************, there is a thread entitled "308QV running hot" ( or something like that) wherein there is a picture of one installed in the radiator. I'm not sure if you'll be able to tell if yours is a match. I would guess that the main issues are the hole and thread sizes and the electrical hook-ups. Good luck!
