John Mummert sells aluminum ones on his site ford-y-block.com at least you know if you buy something from John it WILL fit! 

I love the smell of burning rubber in the morning!

1961 f100 y- block looking for a thermostat housing, if any one has a spare laying around. The one I bought awhile back off of evilbay  does not fit, I know I should have checked its fit when I bought it.
