The adjustable rear anti-rollbar (#909335) blades are to stiff for the 705/Impulse. You will have to change out the male blades for the front (#909216) blades.
Thanks corwin for the update
Ummm, I actually wondered why they took the grub screw out from the new shoe design when 705 came out... The older 2 speed gearbox shoe had grub screws in them. You can screw in the grub screw to make the other half of the shoe nearer to the 2 speed bell housing to make the shifting smoother (nearer) or harder (further). You can actually still use the shoes when it is worned out to a certain extent. Anybody knows what size these grub screws are?
Concerning the adjustable rear antirollbar blades, yes the male blades for the front is softer than the ones that come with the 909335. The bad part about these blades is that you need to predetermine the lenght where the grub screw will lock onto it. This is important that you need to determine that both left and right are equal in length and that they put equal pressure on both sides.
Once I get both lengths equal, I use a sharp object to mark on the shaft where the blades will be locked with the grub screws to equal length. The blades that come stock have grooves which you do not need to measure at what lenght you need to lock the blades.
