Looking for a back half of a muffler for a 064 or 066. I bought a dual port cover but it is different than the muffler on my saw. I believe I have an early version muffler. Here's a couple pics that will show what I need.

Hey man, good evening. Hopefully Kyle can square you away with what you need, but if not and you still need one let me know. I have a new can & cover that came on my 660R when I bought it this past fall. I ran one tank of gas through the saw with it on it then ordered an aftermarket set up and it has been in the box since then. Also, I'm in MD, so shipping would be cheap. Let me know and I will try to help you out. Scott
 
You will need to make a spacer or buy one to use an 066/660 back half on an early 064 KS Jug like you have. The early 064 mufflers were 1/4" deeper than the later ones. Stihl sells the spacer cheaply enough it's not worth making one on my opinion. If you try to bolt it up, it will contact the case mounting holes but be around 1/4" away from the jug. I have almost any combination of 064/066/660 mufflers/covers you could want if you are interested in taking a look.
