Just looked at a 69 coupe no X code. Cowl tag reads
69-12437 LO 617616
715 69-69
11B 681

VIN 123379L508760

Runs and drives, 350, 3speed manual. Needs to have the quarters, outer wheelwells and front fenders replaced. Floors and trunk are fine. The original front buckets are replaced with some other kind of seats. The dash has been modified but is not so bad it can't be put back to stock, heater box removed and the hole is filled, it to can be put back to stock condition.
What's it worth? Thank's DZFool

A junk basket case is 2 to 3 grand . If all the parts are there and reusable probaby between 3 and 7 Grand . Your post is a little confusing what is rotted and what is solid
