Machine Shop Recommendations?

[Speedyn]

Looking for some recommendations for a machine shop to modify a couple transmission parts. 

Need a race’s inner diameter expanded slightly, and a bolt hole added to the gear selector, to match the other ones I have.

You could try Wallin Machine.

If I understand correctly you want to machine a bearing component? Not sure if that is possible/advised but give them a call.

I have done a similar modification 30 years ago. If you need the OD of the bearing larger. And a bearing didn't exist. I had a sleeve machined that was pressed onto the outside of the smaller bearing. In my case it was a roller bearing. In your case it looks like a sleeve bearing. So you would also have to make matching lubrication holes in the sleeve to match the bearing.

   I had it done at Canada Auto. This really isn't that high tech. Drilling the matching hole on the shaft shouldn't be tough either.

Thanks for the recommendations! Wallin is able to do the work. 
 

I’m trying to swap the extension housing from my broken mk4 w58, onto a mk2 w58. So I can use it in a mk4 supra. The mk4 roller bearing sleeve is slightly too small for the mk2 roller bearing, and it’s very difficult to remove the bearing. So this is the easier option.
