Hi MIke
I assume that you are talking about the GMC Motorhomes International parts interchange booklet.
If so, I don't understand why you can't find the information.
Look in the section called Heater and Air Conditioning.
There are listings for the 73-76 and also for the 77-78.
Under the 73-78 it shows the original GM part number as 3036848.
It also shows a Everco number M1847, a Murray number 208902, a NPAP Balkamp (BK) 855-1076, a Stant number 26102, a Four Seasons number 3588, and a blower motor without fan GM 52451060.
I am not sure what you are looking at but it is definitely in there.
One thing you should do when you buy one is to have your old one with you and make sure that the offset of the blower fan from the motor is the same.
Some companies now confuse the older one with the new style. If the offset is different you will get a reduced amount of air blowing in the heater box.

Forgot to say that the 76 Olds Toronado will probably be the blower to fit the 73-76 GMC Motorhome and , yes, the blower does have a hole to cool the motor. There should be a rubber hose that fits into the hole and also into the blower motor housing. This forces cooling air into the motor. If you hose is missing then it is not getting cooled properly.
