Looks like you have a pair for fit up and a pair to use. Glad that your purchase was a success. And as much as I complain about eBay, I've had only one really bad experience - and it was selling an original '57 T-Bird OD tranny to a total idiot that said it was a regular Ford OD tranny - (except I was the guy that pulled it out of the 'bird wreck about 1960). Good luck - keep us up to date on the mods
