727 Lock up converter choices?

by the time I do that plus have them put a new ring gear onto it (which is the whole reason it needs attention) wouldn't I be better off to just get a different one?
IF! Is the operative word here. Finding a new lock up converter is not easy. Probably more so now with the way things are in the world and it’s shortages and delays.

IMO, having a knowledgeable guy restall your stock unit is the best and quickest way to go. You already have the main part, the converter! They will open it up and do there thing. Welding a ring gear on is child’s play for such a professional place.
