Bought a clutch kit from Rockauto and neither the release bearing or the pilot bearing are right (see pictures below)

Where can I find a good new release bearing (and fast? I'm in Canada) & a good pilote bearing?

Might also have to change the rear main seal & output shaft seal (Between transmission and driveshaft)

 

Thanks!

A bit more info would be helpful like what year is your car?

Looks like that new bearing is for an E21-E30 equipped with an M10 engine and 5 speed. Both Blunttech and Ireland Engineering carrie the correct release bearings well as rear main seals for your car and can expedite shipping. 

The pilot bearing may be an issue, people have been receiving the wrong bearing inside the correct box.you should read this:

Think Blunttech and IE are both aware of the problem now, talk to them. Good idea to have the ENGINE VIN when trying to order.

Another option is the closest BMW dealer to you.

If you received  a 5 speed style bearing its likely that the disc and pressure plate are the later style 215mm. Earlier cars have a 228mm disc/plate. better measure yours.  Sorry.

Newby question but how do I measure my flywheel? It does not seem to be the diameter. The only size that fits 215mm is the distance between the pegs on it.

That's how you tell, by where the alignment dowels are located.  If the pressure plate fits you have the correct size  The size is stamped on the pressure plate housing.

So update from me since my thread on the pilot bearing sent me a notification. When i installed my engine in March blunt tech and pelican parts both sent me the same incorrect bearing. I made them aware of it, and at that time it was a problem with the manufacturer no longer having the correct part in stock. Im not sure if this was a temporary issue, or if the correct bearing is NLA. luckily for me a generous member of this forum had a old bearing that he was able to send me. 

 

Fast forward to August of this year and i happened to blow up the motor that i had installed in the spring. When i replaced the motor i ordered gaskets, and a new bearing from Blunt to replace the motor again. Unfortunately as of a month ago this issue has not been resolved and i was shipped the same wrong bearing again. 

 

This time i was fortunately able to pull the old bearing out of the motor from March and reuse the bearing. I was able to do that by borrowing a blind hole puller from autozone. If anyone needs to pull an old bearing make sure you're using this tool as a pilot bearing puller is too large for the pin type bearings. 

 

i was unable to find any pilot bearings from any suppliers when i had my issues, but i did find other bearings that might work on mcmaster carr. https://www.mcmaster.com/5972k276 . Full disclaimer that these might not work, or that they might even have a better option on their website. But spec wise that was the closest i was able to find. Also be aware that this bearing is a press fit, where as the stock bearings are a clearance fit on the shaft. In order to make one of these work i would imagine that the inner diameter would have to be slightly increased.
