727 Pump/TQ Hub Seal Leak

Does it leak running or off? A bad pump bushing can leak off but seal running. A Chevy bushing would center that Dynamic converter a lot better, but .030 is a lot. I've seen the same problem on old cruisomatics that folks would install a C4/C6 seal into and have a leak, because the OD of both seals are identical, but the id is smaller on the cruiso. I researched converter repair sleeves but only found front repair kits for the crank/converter. If you could find one, it sounds like a repair kit for a chevy converter would fit better.
