Where to buy Speedotron small parts?

So my 202VF heads were purchased used and I've ran into a problem here. I don't know that all of the strobe handles that screw into the piece that tightens the vertical movement of the strobes are the same and I think I ended up cross threading two of them so that handle won't screw in enough to tighten the strobes.

I would like to purchase 5 new handles and 5 of those cylinders that they thread into. The cylinders look like they just have a bolt on the outside that's removed and the cylinder pops out.

Does anyone know where I would go to find these parts? Is my best bet to call Speedotron themselves or is there another company to go to?

Call Speedotron @ 312-421-4050. They have what you need. Here are the descriptions of the parts associated with what you're looking for and what Speedotron charged me for them when I repaired a Blackline Light that I purchased off of ebay in April 2011. The light unit was missing everything below the actual light bracket.

#40063 Heavy Duty Stand Block (Anodized) $9.00
#40423 Stand Block Knob (Black) $4.00
#40060 Tilt Handle (Black) $8.00
