B&M 10" converter

I have a 10" B&M Holeshot 3000 converter for 727 trans. P/N 10425. The converter has about 3,000 miles on it. It came out of my buddies street rod and it was cool behind his built 340, but way too much converter for my 360. I switched it out for an 11". Works great! Asking 325.00 and I cover shipping to a US postal address
