I knew it was something....

Since Tom and I first talked about this, something kicked up a parity error flag and it has taken me a while to track it down...

Where Tom put blowers is where 73&4 have the MAX AIR outlet part tacked on. That piece it essential if one is to have any A/C performance at all in the older coaches.

We have a 75 with the 'max air' opening and the goofy scoop thing to direct it upwards from the floor.
Since that's what we use 99% of the time, it was a concern for me too.
There seems to be enough room between the scoop and the engine hatch opening, and I was also considering partially recessing
the blower into the floor to make it less of a giant lump. If you don't have the scoop though,
you'd risk having all your AC output being sucked back into the intake of the new blower.

Looks like it's still workable to me.

I was just comparing this to the other modification, where you mount the OEM blower on the front side of the case.
The problem with that is it's sucking air through the evap instead of blowing it, and we were concerned about
the water/vapor going through the blower motor. Short of a major rework or replacement of the enormous OEM box,
Tom's idea looks like a good improvement.
