I removed unwanted metal from the nifty little Daewoo Automatic differential, it's quite small (about 100mm diameter) there are 4 holes already in the end but they are either too large or blind so I will drill and tap 4 new M10 X 1.25 holes. The left side of the spool will bolt up to the diff. end which will hang off the spool, the spool will be supported by 2 X 1 5/8 self centering 209 bearings in 209 Pillow Block Housings.
