Yeah, throw em this way. I could use some more short ones.
The fenders from a Suburban will work for you. A Varsity and a Suburban are essentially the same bike.
A lot of suburbans have color matched fenders with white stripes, black stripes, or gold stripes, so you might have to search a little bit to find exactly what you want. But chrome ones were offered too, so you'll just have to see what turns up.
The later 70's models often came with the short fenders. They could have been added onto a fenderless original bike or full length tourist fenders might have been removed and the bike updated for a more
modern look... in 1980.
The original tires would say Schwinn Puff 27x1-1/4 (yeah I know, puff? Really?). They're VERY hard to find in decent shape. Plenty of modern tires are available to fit those rims- I assume you mean 27 not 24" - in lots of brands and styles.
I use Niagara Cycle for a lot of mail order stuff now- they're very reasonable and ship quickly.

If you're looking for anything for it drop me a line, might have it.
Good luck with it,
