Over the last couple of days I was able to get the heater and the wiper mechanism installed.
I got a nice set of gaskets from ANG on eBay, they worked great. I found order of assembly is important in this area and forgot that the wiper came out before the heater. After installing the wiper mechanism I found the heaterbox wouldn't go in. The 'aha' moment (assembly is the reverse of dis-assembly ) occurred, so I took it back out and got the heater installed first. The wiper assembly then went in easily.
I also installed the wiper motor and gearbox and ran the wires up to it and fastened down the grounds from the harness that attach to one of the mounting bolts.

I wish I had this picture from when I pulled it apart, would have saved me some trouble
