I've been trying to find a way to get replacement parts for the SMDV 100cm Dodecagon speedbox -A100 and its quick release.

For the quick release, I need replacement thumbscrews.

For the softbox, I need 3 replacement rods and and the white outer diffusor piece as it's gotten dirt stains from falling in the wind.

If you can't provide selling just these parts, if you could point me in the right direction, I'd really appreciate it.

I love smdv equipment, so hate using other equipment due to struggling to find replacement parts.
