Absolutely, I've got 12 new crush washers.
Update: did the brakes yesterday, and I learned this the hard way (almost). I'm pretty sure it is 30 in. lbs. and NOT ft. lbs.
As I was torquing the bolt down, I felt it become super tight and then severely weaken. Since the head was in tight, I left it, but then I had this nagging suspicion that I didn't trust it, so I took it out.
Lo and behold, the new banjo bolt was semi-sheared and deformed from the top. Any further, I would have definitely broken it off in the caliper hole. Thankfully, I reused the old banjo bolt (with the new crush washers, of course), and this time, I started to ramp up the torquing instead of just going straight at it. The bolt almost started to do the same thing, but I backed off immediately.
All is well. New calipers and stainless steel hoses have been installed and tested successfully. Thanks so much again guys!

Bummer, man. That sucks. If it helps, I just re-checked the torque spec and it's indeed listed as ft. lbs. for the banjo bolt
Reminds me of one of my favorite sayings: "If you can't fix it, force it. If it breaks, it needed replacing anyway."
That is a bummer. Makes me feel bad I looked it up in the shop manual. If you didn't have it, you likely wouldn't have ruined that banjo bolt (or worse had you not used your experience to know something wasn't right).
Like Dave, I went back to my source and confirmed it was ft/lbs. That is filed away in my head for the next time I am working on the brakes.
