Hello Kathy, thanks for reaching out. That does look similar to a bulldog jack, but I did not find any reference for the part number you provided, so I cannot confirm what brand that is. Without knowing the brand it is not possible to recommend a replacement gear kit. Even if we did know the brand, it is likely that a gear kit is not available since the jack is so old. In this case your best bet will be to replace the jack entirely. The Square Jack # TJD-12000SP-F2 is a very popular square jack. The outer tube is 4" wide, it has 25-7/8" of total travel and a 10K lift capacity. Please take a closer look at your jack and confirm these dimensions.

Hey Kathy, did the square jack you looked at match the dimensions of your old one on the Cato Classic trailer? Knowing how the fit turned out could help others replacing older welded jacks too.
