Different size torque converter knob 170 vs 225?!? Are you kidding me?

Call Dacco at 1-800-443-2226, and ask about a converter for a TF-904 with a 1.550 pilot and 27 spline. This is a "stock" style converter. They might be able to adjust for a little more then stock stall speed. They used to have them available, but I can't find the part number right now. Was priced around $100.00
