Trying to find the correct gasket/seal for 1980s (house built in 1988) pella casement windows. Appears to be insert (with a couple barbs) and 90 degree "tab" for the seal.

We may be able to help, but I cannot identify your seal from this picture. Could you remove a small piece and show us a clear photo of its end? Seeing its profile from the end would be a huge help. I will also need your measurements. Thanks!
