Hi, I am new to the group. I have an X33 1969 RS Z28 that I am having restored. I am interested in originality, it will not be a hanger queen but driven a less than 400 hundred miles annually, and price is an issue. About the car. It is numbers matching engine and transmission. It has 44,700 miles and I have owned it for over 23 years. It was built the last week of January 1969. It will be repainted the original Hugger Orange/Dover White and has the endura bumper. The firewall still has the assembly line markings as wellThe original starter is being rebuilt and I have the original master cylinder in need of the same. It does not have power steering and has the base interior. The only non-original items that I am aware of are 2 of the wheels were replaced with painted over chrome rally wheels before I owned the car, a rosewood steering wheel, and the battery (I have the original but dead). It had headers when I bought it but they are rusted and in need of replacement. I have them off but have not found any markings to know if they were OTC or after market. There is no smog equipment. My questions:
1. Is the value hurt by replacing the entire interior? The carpet and dash pad are a must as is seat foam. I am of a mind to just replace that and the seat covers as they may not survive but have also heard that it might be best to do it all. Sadly, I was in the Army and the car spent time in storage some mice got in and soiled the carpet and ate the build sheet (I know I feel bad enough already). At least that is all they did.
2. I wanted to go back to the original type exhaust but I don't really want the expense of the smog equipment so am considering headers like it has now.
Any input would be appreciated. I like as close to original as possible and certainly do no want to hurt the value but want to keep it affordable. Thanks in advance and I look forward to your comments. Bryan
