The "Nobody will want it" 73 Duster Driver project

Looking good! I remember seeing that car on Craigslist several years ago. If you haven't already done so, put a new pinion seal in it before you fill the rearend with gear lube. The last one I swapped in while doing basically the same thing you are went to dripping after it had been retired for years and then I put it back to work....lol.
