Does anyone know where I can find a rebuild kit for these things?

just thinking about fixing the wiper pisses me off.
I had bough a newport engineering electric wiper kit to swap out the vacuum unit, I had either misplace or threw out the good working vacuum unit, so I bought a use one from ebay, I want to go thru it before i put it in.

this was few years ago, the newport unit work great for 30 minutes, then it would slow down and stop working, I sent it back to those clowns for warranty repair, they sent it back saying they tested the motor and found no problem(i am pretty sure they tested it with no load to the motor) , re-installed in my car 30minutes into the drive the motor shorted out completely, poping fueses. this is some expensive wiper motors that only work for 1 hour total. not to mention I had to go without wipers in a downpour.

if you notice the motor is painfully undersized for the job, even my tiny toyota mr2 have a motor 4 times the size for the wiper.

I also could not find any NOS or rebuild electric motor for the 1961 Fairlane 500, I could convert it myself then. I acutally bought a reman unit but the mounting is not correct for the car and will not work.
