You could ask these guys, the fellow that did repair work for Hardys BC does the repair work and may have the parts you need. I had a Uniqua get a new handle and fix the latch there few years ago and was happy and they are on Island so close. heres link. Teddy's Tackle - Fly Fishing & FlyTying Supply
Might try Mikes Reel repair in lower main land to they used to have some of the spring packs last I looked at site.
I Have dealt with salarseeker on ebay He is in eastern Canada and has a lot of hardy parts, You can message him on ebay with what you want and he will give you a price on that item and list it for you.
