Does anybody remember what years the hd. K case th350 was made? I broke mine in half by the modulator, and am looking for a replacement and in my neck of the woods it's pretty easy to find a whole parts truck for pretty cheap. I found a k10 with a 350/205 minus motor for $350, but it's 60 miles from me and my d.d. only gets 8mpg. 2800rpm at 60. thanks in advance.
