Hi Al!

Unfortunately, Bulldog's parent company (First Brands) has had some... "issues" as of late and their parts are basically impossible to get ahold of. Look them up online and you will see what I mean. Due to all this, we have taken all their parts off our website. Hopefully they come back at this point, but who knows.

That said, I did a cursory look online and there may be some still available elsewhere. However, I would call however says they do have them to double check. This has been going on for a while now, so it wouldn't hurt to make sure they do actually have them.

If it turns out you can't find one, the only option we have would be to replace the whole jack with something like the etrailer Square Direct Weld Trailer Jack - Drop Leg w/ Spring - Sidewind - 15" Lift - 12,000 lbs # TJD-15000SP-F. This is nearly identical to the jack the 500212 gear kit fits, so if worst comes to worst, it will be your best option.

Sorry I don't have a better answer for you. What kind of trailer do you have this jack on?
