Blower motor: where to buy?

[Tpo]

Well I’ve been learning about electricity, thank you guys. The heater fan motor in my 60 is popping the 10A fuse as soon as you switch it on. It will twist a 15A fuse and pop it after a minute or so, all the while failing to spin the motor. I yanked the motor and bench tested it, it is harder to turn by hand than youde think it should be, though it runs straight off the battery. The 14? AWG wire I was using heated up a little though. So I took it apart, cleaned things up and now it’s worse, lol. I called around and the days of rebuilding electric motors are long gone. My local stores don’t have it, and a local Chevy specialist has a motor but the bolt spacing is an 1/8” too small, and the motor is 1/4” too small in diameter.
I called LMC and the only specs they had were shaft diameter and overall length, and theirs is shorter than the OG. I’m not sure what to do. Anyone here purchased a new blower motor recently?
Mine is a deluxe heater in a 60. I believe the 60-63 deluxe and recirculating heater shared the same motor, correct me if I’m wrong.
Thanks!
