I'm planning to do the same. I actually already have ordered the parts to do it!
GroundForce makes them!
This is the answer I got from them dec 2:nd:
We have a kit available. It is part number 9984. This kit is actually on backorder right now. Please allow a few more weeks for us to get all our parts in.
Also have a Mopar body kit at the painters ( wont put it on until the snow is gone ).
So I'm waiting. And as other members have pointed out, we have snow in Europe every year!
At least in Sweden where I live.
So it's nice to have a car that can crawl in the snow and still look good!
