I think it was Bubba that had a bad experience with houser. Houser was advertising that his gears would work in the older style pumpkins, Bubba bought one and found they wouldn't. He did get his money back. At the same time houser was stating on his website that he was the only one who was having the gears cut, he wasn't. Randy's Ring Pinion was making them too. Personally, I would not do business with houser beacause of this. My recommendation is to find a pumpkin with 4.10 gears or better if you're lucky, and make the swap. Best bang for your buck.
With the price of a new set of gears, you would be better investing your money in a late model differential and having it narrowed. There is a 3.5 inch difference in width, a 1.25 difference in setback and a 1.5 inch difference in wheel width, it adds up to a narrowing job of 2.5 inches to maintain the same centerline on your rear wheels.
