Looking for original A/C blower motor for a '71 Challenger

[Duodec]

I'll try to post pics and part numbers tonight.  Don't need the squirrel cage fan but won't turn one down.  Same with the triangular rubber gasket on the mounting flange; I'll take one but don't need it. 

What I really need is just the housing parts (specifically just the back housing) in good condition, so a nonworking motor would be ok; its going to become a 'parts' motor for mine.

Aftermarket not needed; I have one NIB and its appearance and construction are totally different

Thanks!
