1982 CR 500, to rebuild or not to build, that is the question

I just picked up a '82 CR 500 and an '81 XC 430 off of a craigslist add that read "2 WR360's, $600 for the pair". I noticed in the pictures that one of the bikes had 10 fins and a silver frame which peaked my interest. So I went on a little road trip and discovered that the one bike was indeed a Silverstreak based on the frame and engine numbers. The other bike is a 430 xc...... Both bike have missing parts pieces, but the 500 is the worst, looks to have had the kick back broken center case issue, the original tank has been repainted twice and has dents, along with a bunch of other issues. My question is, is it worth rebuilding? I paid 200 bucks apiece so I have some room for rebuilding the 500....any advice and comments welcome.
Thanks,

Nice find for sure.
If they were mine, I would restore not just rebuild. The SS is an iconic Husky, highly desired. Having both frame and engine with numbers is a great start. A nice SS tank alone is about $800. I would guess a restored SS might sell for $4000 - $5000.
Beyond the value, I would restore just to save a great looking Husky.

Restore and rebuild both I would. They enjoy the rides for decades.
