The Tokico and OEM clutch master cylinder share the exact same part number (MB555133), therefore, is it safe to say they are EXACTLY the same? I mean, hell, one is $130 and one is $60. I've read through posts from years back where someone said they were exactly the same. Any current info on this?

BTW, does anyone know who manufacturers the slave cylinder? Thanks

I've asked the similar question about Nabco and OEM, since Nabco is the OEM manufacturer for our clutch master cylinders. However, never got an answer if the $60 Nabco and the $120 OEM were the same.

They use the same part number so it should be the same part. Otherwise, how would anyone tell the difference from a distributer's point of view.
