Just a heads up on a couple thing I learned when I purchased a used E-Ladder. The SlideMaster jackplates prior to 2008 (BCB can verify the year) dont have the E-Ladder mounting holes drilled in the side. After that, youre good. I had to buy a motor bracket from the company that makes the E-Ladder for my 2007 SM. Total shipped with hardware was $19.00 I believe. Great folks to deal with.Love mine by the way. I had to use it (not by choice) recently. Great addition to any BCB without a ladder.
