They are the same as TL01 (B parts grid).
If you don't have the 2 degrees rear upright I would suggest you buy
p/n 51238 that includes front upright, C-hub, Rear toe in upright and frame spacer to make your M03 into a M03M, all of that for less than 10.00.
All the parts are made of a better material than the old uprights,
you will also need smaller bearings, 8x1050 to be exact.
Hope this gives you all the avenues!
