Part Sources For Vintage Huskys

O.K, lookin at the 510 after readin all the posts about restos. I have lucked out seeing how the husky was not ratbagged from the original owner. I got an incredible deal ( Free, wouldn't start for him after being stored for 10 years). Bit of TLC, carb clean and lots of kicking, running bike. Long story short, want to resto the bike. for most parts, its cosmetic work and lots of cleaning. Tank has the yellowing, trying to figure a way to either clean, paint or replace. L/H number plate broken, silencers are pretty well done. Need good sources for either NOS parts, or good quality replicas. Will be needing decals as well.
Any info or help would be greatly appreciated, Will take some pics here real soon and post up. Great looking bike for 27 years old.
Thanks
