Help with a 1965 nova restoration

I just bought a 1965 nova not to long ago and would like to see if mabey i could get some help i need all of the seats out of one but can't seem to find any also i would like to know if it would be difficult to fit a 350 small block in it, it originally came with a v6 in it. it does have a camaro front end under it so that helps a little. if anyone has parts for a 1965 nova please let me know what you have because i need alot of parts

Thanks
