Sourcing new P clamps for '77 CR 390

Hello all.
I joined the forums when I bought a 77 CR390 a couple of years ago, but haven't had a lot of time lately to check in.
I was wondering if anyone could recommend a good source for new P clamps for both the rear fender and the inner fender. I haven't checked this myself, but I was told that the frame diameter is different at the rear fender and the inner fender. I know DC plastic has them, but it seems only in one size.
Thanks for your help.
Peter
