It takes a lot of work to build them, but for that price I too would want a better spec sheet. I love the color, and it has wow factor from the street, but I wouldn't want things like bedliner in the interior, (very unoriginal) and uncomfortable, (I would want carpet to dampen the heat and insulate, they are very noisy without insulation and carpet). For that price you should be able to get 1977 a/c put in it.
They talk about the body lift as a good thing, i suspect they had to do it to clear the 351 and C4 but I had linkage problems and steering correction needed when I installed mine. ( to fit the automatic)
If she wants a driver this one may not be the best because of the detroit and limited slip, It will not ride smooth (they never do) it has heims on the steering joints which I loved on my wheeling rig but would be careful with on a road rig.
It's pretty, and you know old cars so if she isn't expecting a smooth ride, quiet ride she might like it. I would still swap in (this sounds wrong on this forum) open diffs or a selectable locker for a all road rig.
