Headlight Question!
 

I've been trying to find a definitive answer, but my search game is slipping. I have a 97 E250 with 5x7 sealed beam bulbs. I found some Hella 7x6 H4 bulb housings. Will they fit? I know I'll have to get a conversion loom as well... I'd like to keep the smaller headlight if possible, I just like the look better... TIA for any/all help!
