you are doing the same set up that i have. i had my 3"SL put on then put on the 2"BL. Rode around for about 3 weeks and had to get the tires on there to fill up the wheel wells.
Im glad i did the SL first because it gave me a few more inches under the X to move around with tools to do the BL. Get some pics up when you are done.
Good Luck.
