Engine bars

Hello, in seeking out some engine bars, I keep discovering new and various types. 
Anyone know what would fit an 83 KZ550 shaft, and an 82 KZ1000 CSR?
also looki g for a set for my 750 twin, but my big priority is my son's 550

Bump

The fitment list that came with some NOS case savers from MC Enterprises indicated that they fit various KZ650, KZ750-4, and KZ550 models including the 550 Spectre.  I assume the list is correct.  I got them for my KZ650-CSR.  The 750-Twin fitment is different >> I bought a set before I knew the difference. doh.  The engine guards from any 750-Twin will probably fit any 750-Twin model, since the engine was virtually unchanged thru the entire model run from 1979 to 1984. but don't quote me on the fitment.

ps: you might be able to contact MC Enterprises assuming they're still in business. I vaguely recall talking to someone there on the phone about the set I got prior to purchase. this was more than 10 yrs ago. 

They are available but I guess shipping from Italy would be a killer
