Springs for ShoBud Super Pro

[George Madrid]

Hi All!
I am fixing up a Superpro. I am looking for return springs and raiser helper springs.
Does anyone know what type of spring/s I would need for this? Any help would be greatly appreciated.

Also side note: Anyone got aluminum Knee Lever Brackets? I'm looking to upgrade from the pot metal ones it currently has.

All the best!
