Looking For A Cam Chain Guide

This is probably a long shot, but does anybody here have a spare cam chain guide they would part with? See part #4 in this diagram (12053-1001):
 

The engine I'm working on is so old the bakelite(?) surface of my guide has come off, and everything I've seen is way out of my budget; this part is in the 1979 KZ400 H (LTD) parts diagram, but would other guides fit as well? Any help or info is greatly appreciated! 

I'm pretty sure you saw this, but just in case.

Damn.....................

Edit: Also found this. Looks like but not sure. It's an engine parts, so look like doesn't count. Only way to find out is to buy it and compare...............

Yeah, $130 is pretty much "Damn"!   And the other Japanese site wants 100 yen, (less than a dollar!) but I'm kind of iffy on that one, Ojisan; and it doesn't look like the right one anyway - note the difference in the base/fastener hole. Thanks for the research though. I have yet to try the local bike shop, see what they have to say. 

This 'KZ400 LTD' ("Limited") is definitely that - Limited!  

Although one just did pop up on Ebay for $46 - part number 12053 - 002. Looks very similar, but I'll have to check it. (Still - $46; Damn...!).

The part used on the earlier bikes (12053-002) looks very very similar.  Maybe they just tweaked it a bit for the 78/79?

I was looking at ebay to look for what I need, but came across this so I figure I'll post it here. Seems bit pricy to me as my bike is late model KZ, but I thought it may be worth mentioning it since you guys are looking for KZ400 parts.
