Templates to design your fan shroud

Internal mount or external mount? Cross flow or top down set-up?  Complex curvature and metal shaping or super simple and cost effective? 

We are going to have some questions before we start constructing so fill out as much as you can and scan, take a picture with your phone and get us some numbers so we can get designing.
