Sharpbuilt shroud machining

[fast70]

Hi,

I recently purchased a used sharpbuilt shroud and had some questions regarding fitting the unit. What I got was a 911 11-blade fan, a sharbuilt shroud, a base plate, sealing tin, and fan strap. However, I did not get any instructions. I was wondering if anyone had a copy that they could scan and send to me? If not, if someone knows how much to machine the breather tower? How to attach the baseplate? I have 4 bolt holes in the plate but when I look into the breather tower theres nothing to bolt them to - something I'm missing? What size pulleys do I need to use?

Thanks for the help
