Question for you experienced FABO guys out there

I am looking at different two cars.

Both have no engine. One comes with the original 4 speed the other is set up for auto-column shift but no tranny.

I want a roller to fit my own powertrain so really the difference is the trans tunnel work for the auto car

One has almost all the body work done but no interior (and needs trans tunnel)
The other has the original interior which is mostly OK but needs 1/4's on both sides + full body strip/fix/sand/paint

QUESTION: Which is more expensive, body and paint or a full-on interior re-do with 4-speed trans tunnel install?

I know you guys have been through this, any feedback is appreciated.
