Thought I'd fill in the results.
I ordered this from that other place (
http://www2.towerhobbies.com/cgi-bin...?&I=LXFCC1&P=7) which is part number 1147 from MIP. The package arrived w/ that part number but the description on the bag was "1/8 rebuild kit" (or something to that effect). At MIP (
http://www.miponline.com/catalog.html) part number 1147 is typically referred to in different fashions but they seem to contain "monster truck coupling rebuild kit. "
In summary, I believe as long as you're ordering MIP part number 1147 you should be fine. :D
