Based on the limited info in the ad I would say the car will sell between $20-25K.
This is certainly not ALL of it but here are some tips for you. People want to know these things.
1. Is it all rust free original sheet metal, if not how was it repaired and when?
2. What is the condition of the trim?
3. Is it the original engine and trans? If so, what are the numbers?
4. What rear end ratio and is it Sure Grip?
5. Do you have the original fender tag, broadcast sheet and IBM card?
6. You say no shipping offered? Wrong statement to advertise a car nationwide on the
Internet. You have to be willing to offer help with having the car available for a
transporter. Buyers expect to pay the shipping but the way you serve it up is very
negative.
I sell a pre-purchase checklist for people that want to try and buy a car long distance. It is some thing that serves the seller as well when preparing to sell a car that the will advertise nationally. Many people buy cars like this without their own personal inspection and have them shipped, but to put their minds at ease you have to have ALL of the info available to them when they ask as well as many detailed close up pictures. You should also have the car put up on a hoist and take a lot of pictures of the under side of the car noting the rust prone areas.
Here is the web address for the pre-purchase checklist.

You are asking the price of a low #1 or high #2 car. From the description of an untouched high performance engine with 129K miles, the car falls in the #3-2 condition. This is based on the following catagory definitions.
#1 EXCELLENT: A close to perfect original or very well restored vehicle. Generally a body-off restoration, but a well done body-on restoration that has been fully detailed may qualify. The vehicle is stunning to look at and any flaws are trivial and not readily apparent. Everything works as new. All equipment is original, NOS, or excellent quality reproductions.
#2 VERY GOOD: An extremely presentable vehicle showing minimal wear,or a well restored vehicle. Runs and drives smooth and tight. Needs no mechanical or cosmetic work. All areas (chassis not required) have been detailed. Beautiful to look at but clearly below a #1 vehicle.
#3 GOOD: Presentable inside and out with some signs of wear. Not detailed but very clean. Body should be straight and solid with no rust through anywhere. Shiny, attractive paint but may have evidence of minor fading or checking or other imperfection. Runs and drives well. May need some minor mechanical or cosmetic work but is fully usable and enjoyable as is.
#4 FAIR: Runs and drives OK but needs work throughout the vehicle. Body shows signs of wear or previous restoration work. Any rust should be minimal and not in any structural areas. Cosmetics, body, and mechanics all need work in some degree.
#5 POOR: In need of a complete restoration, but is complete and not a rust bucket beyond repair. May or may not run and drive.
