Need help. Fan hitting shroud.

[rs74]

I recently took a cab, dog house and drivetrain from an 87 R10 longbed and put on an 85 shortbed C10 frame. I have put on all new engine mounts, trans mount and new body mounts. The fan is hitting the bottom of the fan shroud pretty bad. I believe I had the wrong trans mount on so I replaced it with the correct mount which helped lower the rear of trans a 1/4 inch and in return raising the fan but still making contact. There is probably 3-4" of clearance between top of fan and the shroud up on top. It is a 4.3 with three speed automatic. Not sure where to look now. Are there any parts that would be specific to the v6 other than the engine frame stands which I swapped over since they are different from the v8 stands. Body lines all match up good so I can't see body mounts being an issue. I'm just lost on what to look at next.
