Apologies, just got a chance to check on the spring. I checked the part number and its actually for the clutch, I also checked Toyota EPC and the part number should be 90506-12023 (NLA). I ordered the clutch spring as it was really close to what I needed for the brake pedal spring. Found this article about the brake pedal spring brake pedal - https://forum.ih8mud.com/threads/brake-pedal.1260514/.
