Pinion Bearings for 742 with Suregrip and 4.30 ring & pinion?

Hey folks,

Getting every thing ready to attempt my first "chunk" build. So far I have the 742 case, new clutch type Suregrip unit. Timken carrier bearings and races 25590/25520 and soon to order
Richmond 4.30 ring & pinion set from Dr Diff.

Now for my question, anyone know the part numbers/sizes for the front and rear pinion bearings and races? I do like Timken parts but open to other suggestions.

Thanks in advance, and I am absolutely positive I will be hitting my FABO brothers and sisters up for information as I start digging into the project. Boldly going where I have yet to go with my wrench spinning LOL!

Be well,
Pat
