'82 J2 - need front master cylinder

Hi all,

My master is pretty bad, the fluid is all crystallized, I need to replace it.  I can't find an OEM master anywhere, except for some stuff on eBay which mostly looks super-sketchy.  Anybody got a line on a decent replacement or an OEM piece?  I'd ask for NOS, but I'd probably have to give up an organ or two.  

TIA!

Any twin disc 5/8ths master will do the job.  Remember the brake light switch is built in to the mc on J's. 

Is the front master specific to the J, or can I use stuff from a police model?  I'm sure there are some good generic pieces out there, but I'm seeing stuff on eBay from companies I've never heard of that I wouldn't put on a scooter.  Plus, I might need to replace the calipers if the pistons are trash (haven't looked yet), and I'd like to do it all in one deal with OEM if it's possible. 

The P series copsicle master cylinder should work just fine.

So after some digging I found this on eBay...

It's a rebuilt master off an 750-E1, it's the same assembly.

Thanks to OKC_Kent for providing the Zedder info.
