[Too Many Projects]

The trunk floor is seriously rusted out from the back window rusting out and allowing rain in for years, as it appears it sat outside under a tattered tarp for a long time. Replacing the trunk floor would be a must before putting much power to the rear wheels, in my world.

Look closely at the pics and ignore all the flat black fluff paint and you'll see the rust holes I am seeing.

The cabin floor looks great inside, no way to tell underneath with the spray bomb, hide the rust, paint job.
It IS a cool car and worthy of, at least, a thorough preservation of the exterior, or deal with the rust in the quarter panels, extension panel and trunk floor and give it a good paint job.
