I am still putting the motor back into the car, but I also ordered a Thomas Vacuum pump for the brakes. I found one on eBay for a steal at $98, so I bought it and hopefully it will be here end of the week. I will make up a vacuum chamber and get a vacuum switch so it's not running all the time. The pump only draws 4 amps, so it's a real minimal load, and runs on the 12 volt system so won't impact my traction pack.
This afternoon I am putting the motor back in. It's already lined up hanging on rope, but I was busy cleaning up the compartment and went off to visit relatives.
