I went thruogh my Steering boot.... GENIOUS move on my part... LOL
Not that I have had any problems, but Bob came up with a WAY better solution.
Remove the Engine compartment fuse box and toss it aside... then, double, triple and quadruple check the area behind that and the inside to ensure you dont drill into anything remotely important.
Then drill like 5 holes. Use one with a rubber gromet, and fill the others with 4 bolts...
And viola! Expandability.
Also, can you post pics of your backrack and how it attaches to the bed?
