Yes, they are the same.If your not planning to already,do yourself a solid and go to the parts store,order up a siemens PM102 blower motor. About 25$ or less. Take a dremel with fiberglass cutoff wheel,or tool of your choice, and open that firewall hole up about 3/8" all the way around,spray it with some clear to protect the bare metal from the trim. Stuff the bigger motor in there with some gasket maker or cut a piece of material to custom seal the larger motor to the firewall. Best bang for your buck upgrade I ever seen,especially since you already have the heater out. I would replace the core too,mine was like 30$ from autobone. Again,since it was already apart, definitely worth the peace of mind. The best 50$ I ever spent on my jeep. There's plenty more information in the sticky or search function.
