Which vendor? I'd be interested in seeing more about it, but most people here are using the GM pickup motor, I think. Since that's the one that was tried by a few many years ago, it's been the most popular swap.
If this one is as/more powerful than the piickup version, and fits better, more power to it!

I believe your vdo pm105 crosses over to the four seasons 35587,it is also from a 1977 CHEV. C10 SUBURBAN It works great!
Good luck!

Followed a couple of quick clicks on that link and discovered that motor will fit a 1973 GMC C15 / C1500.

It fits something like 5000 GM vehicles.


and 66 to 77 Ford Broncos with slight modification ;D

what I did!

I upgraded to Four Seasons Part #35602 Blower Wheel
Four Seasons Part #35587 Blower Motor. Bench tested before installed,Works
great, plenty of air flow, 2x original. I am sure you know the heater housing opening has to be enlarged for this setup to work!
hope it helps!

Perfect:) That looks like exactly the same motor. Did you have to modify the cage at all or was it a direct fit? Thanks!

When you mount the fan on the motor, You will have to position it for the proper depth, So it clear to spin freely!!
Good luck

I finished this upgrade on Sunday. Took about 45 min with the most time used widening the opening for the new cage. Once that was done I bolted the new motor and cage in, hooked up the wires and it blows like a banshee now! Total for parts was $30. Thanks for all the info Tomdee. This is the cage I went with.
