Today I had the very dubvirus "pleasure" of replacing the clutch master on the 71, The old one ( marked Nibco Japan and I believe it's the original, For a fact it wasn't replaced at least since the very early 90's )started leaking from the back.

Picked one up from Oreillys and pulled the master out, compared the 2 and there is a significant length difference between  the two.....the original is about 3/4 of an inch longer.

So I need to swap the shafts.....but I got no snap ring pliers on hand, went to a local oil change shop and one of the techs graciously let me use his.

Question is...is this a fluke or all the clutch masters sold today are like that?...wrong out of the box.

 

This one from MSA was a direct swap and perfect fit. I also replaced the slave at the same time. If you do the slave make sure you get the correct one. The stock '71 has an adjustable plunger and return spring. KEEP YOUR SPRING, it's no longer available.

Interesting...going by the (msa) pic its identical to the one I got from O'reilly's...except the price is over 4 times as much.

I had the same problem a few years ago on a 98 rav4.  I managed to get a rod from a used Nissan Z clutch master that worked fine.

Many common Japanese car parts are interchangeable between vehicles as the manufacturer is usually not the brand on the car.
