Which Rear Master Rebuild Kit for the '83 KZ750 L3?

There are so many 750 models in Kawasaki's 1983 line up. I need to get a rear master rebuild kit for my L3. Does anyone know which rear master rebuild kit is the correct one? Ebay ... Amazon ...

TIA

That bike has a different master cylinder kit compared to many other KZ750 models.  You can check part numbers on Partzilla or similar.

Before spending money on a kit, you may want to look inside with a flashlight to see if there is pitting in the bore.  The aluminum corrodes when people don't change their brake fluid regularly.  On my 750, the bores, both front and rear, were totally thrashed.  And when buying used masters off ebay, for the rear, I had to buy three of them before finding a good one.

I looked up "1983 Kawasaki KZ750L" on brakecrafters.com and it showed 5 caliper kits for rear brake.  Different model?

Oh! Will those kits work for the rear MASTER CYLINDER as specified in my post title and post?

Tourmax list the below for an 83 "L" and it references the CMNSL part number also

Sorry, my bad. I recently put a kit in my rear caliper, had that in my head, and read your question too fast.

That kit claims to cover two different Kawasaki PN's.  Both 4320-1019 and 4320-1035.  Why does Kawasaki have two PN's that can be covered by only one?  Or is the aftermarket kit a compromise?

A question for the supplier 

Wookie..just something noteworthy. I'd bought one of those branded Tourmax rebuild kits a few years back and the primary seal was soo poorly molded i threw it in the dumpster. Might of been an odd-ball that missed inspection but don't think i'll ever chance it again.

It's always a bit of a "lottery" I bought "all balls" kits for my ZRX clutch and brake masters, the clutch one comes with just the seals and springs not the piston - the primary seal was a complete "BITCH"! to stretch over the piston and then get it seated right
