I think I understand exactly what steve is saying. Go to a JY and pull and entire TTB Minus chunk and repalce your existing one. If I ever tear one of my POS flange hubs (or Top Hat Hubs) up this is what I'll be doing. As he said its a helluva lot cheaper than the conversion. If you keep your existing chunk you don't have to worry about gear ratios being different either.
