T5 trans Ident
 

I'm trying to core out my old T5 to get a rebuilt 330 ftlb rated unit. In order to get the core refund the transe must be a "world class" transmission. I checked the tag and it gave me # of 1352-208 which means it should be a WC out of a 92-93 mustang. But what I don't get is this... when I called the trans company to confirm whether or not i get the refund, they told me it would not be a WC trans if part # LM 67010 was on the front of the trans. (stammped on the back of a bearing race of a gear housed in the front just below and to the left of the main input shaft.) Sure enough the part number was there. The blocking rings are made of steel (at least they seem to be, the're black and not brass colored).
If anyone can tell me what I have on my hands, WC or non-WC and whether or not I could get my core I would appreciate the help.
