Suzuki 2 Strokes

I need a few parts for my '71 T500. Hopefully someone has some:

Headlight beam with good filaments - My high beam works, but my low beam and parking light are burned out. Is there an upgrade to a replaceable beam that I'm not aware of? I want to retain the original headlight bucket.

speedometer- my speedometer works, but the lens is broken out of it. If I can get just the housing, that works too.

headlight ears that aren't bent up or super rusty (do these even exist?)

flasher relay- I need one that works. I tried a 3 prong from the auto parts store and it blew the fuse. I'm thinking a 2 prong relay might work if I skip the ground. Can anyone confirm this? I don't want to break anything more than I already have.

Thanks,
Eric

A few updates seeing as how this info seems to be hard to come by:

The headlight wasn't sealed beam, but the bulbs were NLA. I came up with a 35/30W bulb that should work instead of the 35/25W bulb (A5676). I bought a case of 10 if anyone needs one.

The flasher relay was easily replaced with a 2 prong relay. Ditch the ground. Orange to the + side, blue to the - side and it works.

I still need a speedometer and headlight brackets. I'm going to give cleaning the rust off my brackets a shot, but I don't have high hopes.

Somebody must have a speedometer on a parts bike. Please?
