My loss is your gain. I have a 9.5" PTC converter that was never installed. The part number is ptc95-700-27-17-0-sl-sbp and I have been told this will work nicely with a 62 to 70mm depending on the RPM range. The best way to determine if this will work with your application is to call PTC directly and reference that part no. You can read my signature and get a general idea of what I had. Price is $825 without shipping and paypal fees.
