FINALLY, got it home!

All I've got to say is the guy you bought it from isn't much of an Iowa farmer - he could've planted a crop in the dirt sitting on your Duster!

Seriously, nice find! But now you've taken the 'Before' pics please wash your car. If you live on a hill you may want to warn the neighbors downstream of the impending mud river heading their way.
The interior looks like it should clean up nice.
Post some 'after bath' pics.
What're the build plans?
