Need Rearend Help

My trans guy tells me I need to be running a 373 or a 410 gear with the setup I plan on running. (700r4 no lockup, 33x21.5 rear tires ,air ride tech 4 link with bags,zz4 crate motor). Rearend is what came stock in the truck (88 c1500 chevy) 273 gear according to the glove box tag.

Talked to a rearend specialist about putting 410 gears in my housing and was told everything needed to be changed inside .The est for that was $1200. If thats the norm thats fine I can bite the bullet and have him do it but I just wanted to know if I have any other options, like getting a used rearend with 410 gears .are they readily available? I would rather keep my old housing for fittment reasons (everything has been mocked up with this housing) tire fittment is a concern.

I know little to nothing about rearends so I hope my questions are making sense.

Any other ideas lets hear em

Thanks Dave
