As for the adaptor...that might be tricky.
I just called Grant twice, talked to two separate people who asked for the year/make/model then were were curt and dismissive. I asked about the part number for the adaptor...the first guy rapidly spat out a part number that didn't exist.
The second person insisted that I just needed the 3314 installation kit (above).
I'm not an idiot (most of the time)...but did I read correctly that I will need the Tuff Wheel adaptor or equivalent? Perhaps they don't make one?
It looks like the stock Mopar one is $100+?
Again, thanks for any help. I've never seen this job done...but I assumed that it wouldn't be hard to get the parts.
