Howdy folks. I have a new 600 I'm picking up in a week. I was looking at the accessory catalog and have picked out a few things. I'm going to start with the front and rear bumpers. They are on backorder but I can wait. I also want to do a full skid set. I had looked at Iron Baltic as that's what I have on another machine but the OE ones seem to be a good value too. However, here's a question. Are the HDPE OE ones a complete set like the aluminum version? The picture in the catalog makes them seem a lot less complete than aluminum but nothing in the details to explain how many pieces in each set. Also, I'd like to do hand and thumb warmers. Does anyone know the bar diameter so I can find the right set or better yet, have a recommendation on brand? TIA...
