This is a PTS Extreme 9/11 converter. The unit was recently checked out by Rusty at TCS and restalled to 3300-3400. I have the receipt. The converter has approximately 100 miles on it. I am the original purchaser. It has my name stamped on the converter. This is not a hand me down piece. I'm switching to a 400 trans. Non-billet lock up. $425 shipped firm. I do take paypal.
