Need a housing for my J2 cast iron manifold. Bolt spacing is 2-3/4" cc

59-59-59

Believe it or not, these are readily available from Fusick

I checked but the bolt spacing is not compatible. I need spacing of 2-3/4"

I'm assuming that you mean the "Thermostat housing". I don't know if this will help or muddy the water, but the parts book for group 1.153, "cover, cylinder head water outlet", shows three parts numbers for 1957.

1956-1958 model "O" Hydramatic (L.H. only) 567604

1956-1958 synchromesh transmission (L.H. only) 567597

1957 All; 1958 2nd type (R.H. only) 570349

There is yet another number used in 1958 which I am not showing, as you said 1957.
