Been waiting for you to give the year every since I asked and had been keeping the links up for you.
This is the manual that will cover all Mopar cars in 1976. You can't say for sure that there is no difference from 1975. The 1976 manual will have all the updated information that a 1975 manual won't have.
This manual will give you the part numbers for everything on your car. I bought a $1295 special gas cap that is listed on eBay for my car for $130 NOS and the special fuel neck lock that is selling on eBay for $185 for $29 NOS.
