We were looking at one as a possibility with an axle gear change and stayed with the 435, but there are some guys running them infront of profab t-cases with a huge selection of gears.

Like Mpetros said, the case is longer on the 445, but there is also a close ratio 435 out there. It's kind of rare from what I've heard, but I picked one up a year ago. I believe it's tagged as a 435A and I think it's the same ratio as the 445
