I like the looks! https://newyork.craigslist.org/stn/pts/d/staten-island-1977-pontiac-lemans-wagon/7200542906.html
For all the work done to it it is not a bad price, but after updating the engine, I would have wanted an O/D trans also. And the only thing mention about the rear axle is Posi 10 Bolt axle. The original 8 3/4" axle, or something swapped in? Also ratio? The 15X8 WS6 rims look good on it. I like the fact the seller changed out the original firebird center caps (or at least the emblems) on them.
Sounds like he was going for stout internals instead of good gas mileage at highway speeds. He wanted a stop-light sleeper.
