My dad lives pretty close to the dam that makes that Kootenai reservoir. That's a long lake, you guys are probably 80 miles apart! Good fishing there.
There is a guy across the boarder from you in Rexford Montana that seems to have lots of mopar stuff on the Montana craigslist. He might usually has whole cars but I be he must be sitting on lots of parts too. I bought a pair of 15x7 Keystones off a different craigslist guy that I plan on using 215/60/15s BFG TAs on the front. They are the large bolt pattern though and I can't do that until I get my front end swap done.
The new wheels really aren't that bad on price when you consider how rough most used ones are.
