Thanks Old Bisquit. Sounds just like I expected. I just didn't want to find a gotcha after I got into the job. The hardest part will be getting the new unit on the roof and the old unit off. I will actually be able to pass it out a bedroom window and right on to the roof. I will be ordering the new AC unit as soon as I get my tax refund.

Install the 4 hold down bolts in corners----tighten evenly in 'X' pattern until new gasket has been compressed by half (new gasket 1" thick....tighten until it's 1/2" which is roughly 40 inch pounds of torque----that's INCH Pounds not FOOT pounds. Bolts should be 'snug')
