If it is going to be just a "toy" for you to run, then I see no problem. Don't expect a friendly ride in it...my 1972 has no power steering or power brakes, and yes...4 drum brakes need more stopping distance. $2000 ain't bad, but if you can get it for less then it would be a good score. Check the clutch linkage to see if it has been updated or is still cable actuated...cable is HARD to get and you can adapt the 1976 and up setup on the bell housing, what I did. As mentioned, check the frame for cracks. They are prone to cracking and bend/flex easy. They can be beefed up pretty easy and repaired since they are c channel frames. Body rust is a major factor, but you can get panels easily.
Parts are harder to find for the Intermediates, but can be had if looking in the right places. I love my 1972, and 1973 is very similar. Should have D44 rear and D30 up front, T15 3 speed was the standard mated behind a factory 304 V8...4 speed was rare, but if it is equipped with it, you have a good setup. Dana 20 should be the T-case. 1972 and 73 were the better years for the 304 initially. Good luck!!
