Got the fan in. I had to go with a high dollar Panosonic heat/fan/light combo. It was big enough that I could turn it in between the joist to get the vent to work right, and the cover still cover everything. I was hoping to be able to do it all from beneath, but I had to go in the attic to hook up the vent. I couldn't get the fan in place with the vent hooked up from below. The customer agreed since it was the only solution other than major ceiling work. Fan cost me $ 261.00 with a discount. I had to make 3 trips in all. I haven't gave him the bill yet though:( Steve....
