Slant 6 225 1-barrel throttle and kickdown springs

Hi everyone

225 Holley 1920 1-barrel carb.

What's the deal with these springs ? I need both circled in blue below (both are missing) but I can't find any info on specs or actually anyone selling them (Mancini/ebay etc) - no-one seems to care about the /6 when it comes to return springs.

So, some peeps have simply applied whatever springs are lying around or what they can find in Home Depot so I'm wondering if this is the go here or if I need to be a little more scientific in my approach here.

I can go and check out my Home Depot equivalent plus other auto part retailers down here in Aussie of course and/or I can get the springs made but for this I need the build specs.

Does anyone know where I can find these springs for sale or can gather some measurements/photos of their OE springs for me on oem springs from your springs ?

Thanks in advance everyone.
