Well, I don’t believe there is a kit for that steering box, you may be able to find the parts but won’t be easy.
How about a brand new one, these are popular with custom builders and those looking for a lightweight box, summit racing, eBay, jegs, and even Amazon sell these,

The gears on your old on are likely worn anyway.
Be aware of the pitman and steering input shaft sizes, and housing clocking that need to match the stock unit and you be good.
Food for thought, hope this helps.
I have a new one bought from eBay and have no regrets.
