81 Kz750H case guards

As the title states I have an 81 Kz750H LTD. I’m looking for a set of case bars/ engine guards for the bike. I’ve seen the set on eBay before anyone posts that but I don’t see those as being worth nearly $150. Obviously they are not made anymore so new isn’t quite an option.  Anyone got a set they would part with? Or know where a more affordable set can be bought? 

Welp persistence pays off, I snatched up a set on eBay for $65 shipped. No hardware and painted black but other than that should fit well. 
What do y’all think as far as hardware? Grade 8+? 

Not a bad score. I have similar guards and they mount with u-bolts around the frame. I'll get a picture of them posted so you can see how...
 

Well these actually appear to mount to the engine mounts on the frame. Direct bolt on, with slightly longer bolts of course. But these should be more than sturdy enough. Maybe even a set of highway pegs on them. 

Yep, I can see that they mount differently than mine. Here are a couple pics of mine mounted.
