Will it work?

Supposedly the blower motor in the heating unit isn't any good so I've been told to find a new one, no wreckers around here keep anything under the 80s so I went to look for a replacement online and managed to find a Siemens '73 blower motor here:
Volvo 144 Blower Motor - Blower Motors - 74 73 - PartsGeek.com

Just wondering if it will fit my '69 model 144?

By the way, I'm 17 and bought a 1969 144 for 500$ off my ex-girlfriends sister as my first car. Turns out they had the dodgiest RWC ever and I've been doing it up myself for the past few months, it's been an awesome learning curve as I've replaced fuel pumps/tie rods, repaired lights and the wiper motor and I can do carburettor adjustments and all now but I was too scared to pull apart the whole heater unit for this one so I got some outside help.

Thanks in advance, Ethan (long time reader but first post)

 

No problems. You may need to do a little modification,but no problems at all.
