I'm guessing you've seen this link - it's what I'm using for a reference for my conversion.
That's roughly what I did, but differences were:
I used a linear power supply - a big transformer, chunky rectifier and a big capacitor.
I used a pavement vehicle speed controller - bags of power
I had the motor with the toothed belt pulley. It took a lot of force to get it off, but I suspect heating it would have released it.
The motor shaft was a bit too short so I made an extension. That also gave me a 6 mm shaft instead of the 8 mm on the motor, so the pulley fitted straight on, with a screw to hold it just like the origonal.
That pushed the motor back from the bracket so I made an adaptor plate, from the two hole to three hole fixing (all M5 and all on the same 42 mm circle)
I didn't modify the end of the motor as the brushes were at the shaft end. If they had been at the other end (good for a few reasons, like avoiding the able touching the belts and pulleys) I would have happily modified it.
The solutions to the annoying snags finally fitted together to make a sensible arrangement. Photos and drawings in my Photo album: Keith's DB_SL
