Nobody is making a window beltline "kit" for the 1977 Electra 4 Door. That being said, we should have the correct materials and it would simply require you cut them to length. In the late 1970's GM was typically using #10-164X or #10-205X for the outers and #10-179X or #10-035X for the inners. PLEASE make sure and compare these materials to your originals to confirm - if you are not sure you can also order samples online. I have put a link below to the pages on our site that shows these materials along with all of the other options we have.
