You will need new headers to fit the winsor motor. The A/C compressor bracket also needs to be changed (not cheap). The upper water/coolant line is different between cleveland and winsor. Try to purchase a thermostat housing that can be rotated 360 degrees. This will allow you to "clock" the t-stat outlet to exit a more direct way.
I cannot recall anything special about the alt bracket. I think I reused my old cleveland bracket. Might needed some grinding to work. I could have forgotten as it was a few years ago.
