I had to switch convertors when going to the the new motor because I had the odd ball 10 1/2" pattern with the welded on snout convertor--any way I purchased a rebuilt DACCO 11 1/2" pattern convertor(part #F48) for $35 & $20 for the core charge since they would not take the other convertor because of no demand these days-- in town here the place Texas
Transmission Parts usually sells to shops so it may be a little more expensive elsewhere ,but I just walked off the street & they sold to me -- this convertor has lasted behind a few hundred horses for almost 6 thousand miles with no problem so far-- the stock convertors are alot more efficent than those stall convertors which are bad choices for a bronco -- I have a pretty big cam & it's borderline with the tight stock convertor-- I feel if you need a higher stall convertor in your bronco the cam is too big in the motor or the gearing is not good enough
