Fan motor doesn’t fit behind the big block valve covers

I didn’t mention it was an A/C car because I am specifically looking for a shorter motor. I stumbled across an old article from “halifaxhops” who used a direct replacement shorter fan motor and showed pics of the fan motor nicely behind the valve cover. He made reference to “New Universal Products” Part number “AH451” but I can’t find it. I sent a message but he may not be active. I think the post was around 2016. Sorry for the confusion Ron D
You can alert him by posting @halifaxhops . He's active, so maybe now he can chime in.
