A worn GM-A body is not a gonna compare to an not-worn-out F-body when it comes to stuff like that. 30 year old car compared to 10 year old car?
But, assuming you have 30-year old bushings, why not try to rebuild the front end with poly, toss on a larger front sway, add a 7/8's rear sway.
This is a huge difference in both feel and response. Parts are under ~$400,
As to your question, you can have your steering box rebuilt to stock or tighter specs, or use a newer GM box, but you'd mix metric & standard fittings. There are companies that specialize in refurb steering boxes for your Chevelle.
