I removed this setup from my 68 GT350 and replaced it with correct hardware. I have no idea what these are appropriate for. I can say my car ran cool as a cucumber even at 4th of July parades with this setup. I never had any leaks but did notice the stain as shown that certainly looks like a leak although never visible. The spacer is clearly not FOMOCO. The shroud and fan are clearly marked FOMOCO. The only marking on the radiator is the square tab I show in the pictures. I am selling the whole set-up for $250 plus cost to pack and ship.
If interested in more photos let me know what you want and I will take them.
