Trying to understand compatibility and availability of brake master cyliners for my '81 323i

I understand from the ETK that the same unit was used on all e21s that year 315-323i. All the ones I can find on the well known internet auction site etc. look diferent to mine, so is there a diference between LHD and RHD?

Lastly where can I find one?

Just buy a new one... old ones are always shhit

Lhd and rhd are different. The outlet ports are on opposite sides

Thats why my links are for and rhd....

Thanks for all replies.

I went for the new one, all the other hydraulics are new or refurb so it makes sense to me, besides, I had master failure on my first e21 and that was 30 years ago, back then a new ATE master cylinder from a specialist called Cooks Ferry Engineering was £70

Good call
