will the brush bar off of a brat fit my 88 dl wagon?  we have a lot of deer around here that like to jump out in front of cars.

Can't say for sure, but I'm guessing no since the Brat is an EA81 and your wagon is an EA82. I'll also throw in my experience with hitting deer as I grew up in Montana. I know from first hand experience that having a brush bar on a lower height vehicle adds to the danger of the deer coming through the windshield at higher speeds. While it will reduce the damage to the front end and possibly save it at lower speeds, it's more rigid (depending on the type) than the front end sheet metal. At highway speeds, it's much less likely to give than the sheet metal so instead of crumpling to absorb some of the impact, it's going to hold it's position clipping the legs of the deer sending it right through the windshield instead of folding into the front end and hood then sliding into the windshield. That being said, I do have one on my Brat but I'm rarely at highway speeds in an area with a lot of deer and I'm super vigilant about watching for them having had more than my fair share of altercations with the critters. I'm not saying don't get one, just saying weigh the pro's and con's.

that's too bad since it is legal to keep the road kill in Washington now, I mean you got to get something out of it.
