Any idea how I can find out what year 2F exhaust manifolds will fit my 78 FJ40?
Switching out the swiss cheese header that is on it.
I have also heard that people machine their intake manifolds down when putting a header on... Is that true? Does anyone know what the flange thickness is on a stock intake manifold. I want to measure mine if necessary so that I know if I need a 'new' intake as well.....
Thx.
