garyt1957 The 3wd is adjustable, so I went with just the regular instead of HL. iirc, it's just a bit smaller size also. I checked them all out in stores, just to know the sizes and shafts. The Ascent comes in 40 or 50 and it does make some diff in flex, even at same. I have the 50A. In fact, if you need it just let me know. Not going to use it. Adapter is still on.
