Awesome thank you!!!!!!

If you read all that you'll discover that the upgrade and work involved has the same result as just using an 80 up blower and fan. Using the obs motor just gets you the same motor with more work involved to make your fan fit. Factory already did the work for you around 1980.

You need to start with your blower motor. All the noise is the failed bearing(s)

I'm not sure which motor you are referring to when you say "80 up."

So are you saying that since mine is an 83 2wd half ton, motor upgrade would be no benefit???
