Thanks once again to mrclean, who tipped me off to a set of used Ravine aluminum wheels listed on craigslist over in the metro-Detroit area. He then further helped me out by picking them up for me. We'll be meeting up this week so I can get all of these great parts for Mira's XJ. Of course, I haven't gotten the parts storage bill yet.
SO, Mira doesn't even know this yet, but the tentative plan is to move the set of mint-condition Ravine wheels and 31" BFG KM2s from my LJ over to her XJ (since the tires are already mounted/balanced), and get a new set of 33" KM2s for my LJ in the spring (on the set of Ravines that mrclean found for me), providing my tax return allows for buying the bigger tires.
I can't thank you enough for the parts help, Travis. Mira is going to be very
excited when she finds out about the wheels & tires.
