Dan,
It looks right, BUT you need to put some thermal compound on the new rectifier and bolt it down to the plate. I used one of the original threaded holes that mounted the 3 phase Bridge. Be sure to use some heavy gauge wire.
I would bolt down the bridge but it may be ok for testing. The resistor across the capacitor is to bleed the voltage off of it after you power down. Be sure the leads do not contact the cover.
For those wondering what pictures he is referring to, here are pictures to my conversion of the same machine.
