Budbon, what WILDBILL308 was trying to tell you is that you may find that the headlight ass'y is from a domestic vehicle not a Winnebago specific part. As soon as you ask for an RV part the price is likely to skyrocket. Your headlight assembly might be from a Ford Taurus or a Chevy van or something, you may be able to get one for pennies on the dollar from an automobile salvage yard by finding the part numbers on the good one knowing that there will be a right and left part # you will have enough info to find the proper part.
