Just to see if it would work, we put 7/16" nuts between the engine and the "Spicer plates." Worked great for the exhaust manifolds and moved the fan clutch away from the radiator enough that I am going to leave it alone instead of cutting the valence to move it forward.

We have been making a fan shroud yesterday and today. It might be done next week and I will show pictures. Then the engine/NV4500 get to come back out so we can clean everything all up and put in new oil seals.
