'82 KZ750 CSR Twin fork springs

In my journey through revitalizing this bike, I've thought about changing out my fork springs. Problem is, I'm having trouble finding any for my bike. Plenty for KZ750A/B/C, but none for M . I'm wondering if the A/B/C forks were similar enough to the 82 twin's that I could simply use those. Yay/nay/other?

Thanks!
