While the 62-65 manual steering box is getting some attention, I need to know who would know the CORRECT size for the fill plug. The threads on mine are partially gone AND cross threaded. I spoke to the people at Firm Feel, (Great People) and they say it is an oddball size and they prefer if possible, I make the repair before sending it to them, for rebuilding. That little defect is something they would not likely do. I am looking for the best recommended fix. Hopefully just an oversize pipe plug. Thanks in advance Thunder
