Thanks Jeff, Kai and Vance for the OD info. The request originally came to me
from a fellow who is selling a jtype on ebay right now. Turns out it is a 27
id # and he thought it was from a tr6. He was very interested in learning the
differences since he fell into the trap that I did. i.e., someone told me it s
a TR6 jtype so I believed them. I'll pass the info to him.
Thanks again!
