Is it possible to fit C4/C5/C6 in my '75 coupe?

Yes. I have read hundreds of posts on this forum about putting other seats in C3s. Are you actually asking for instructions or pictures of other seats in C3s? If so a search on this website of seats and/or seat installation will show you what you are looking for.

Corvette Fever Magazine has a detailed article in their 'project car" site on installing C-5 sport seats in a mid-year C-3

I installed a set of C5 standard seats last fall. If you can live without the power features, attaching them to the C3 tracks isn't difficult.

I've got some pics of my install here.
