Flip kit question?

[rs74]

I am in the middle of putting the axle, springs and flip kit together. It seems that the axle will not seat down in the saddle due to the saddle legs being too long and bottoming out on the bottom side of the original spring perch. Drivers side is about 3/16-1/4" from resting in the saddle and the passenger is about 1/8" from resting. I assume that I need to take the saddles back out and start cutting them down until the axle rest in the saddle. I don't have a good way to cut them down. All I have is a cut off wheel on a 4" grinder. Here are some pics of the gaps. First two are drivers and next three are passenger. Passenger are kind of hard to see. Bad angle. Any advice before I start cutting. Do I need to cut equal off both sides of the saddle.
