[Truckin']

I believe we found our J roller at Lowe's but that was after looking around at a few stores.

When you get yours I think you'll see the depressions in the doors are not definitive. There is room to go up or down in the slope of the indentation. There is at least one person who successfully eyeballed the placement of their BSMs. There is also at least one person who's gotten them on crooked. I preferred the measuring method since they are so expensive and I've never done anything like this before. It's you're truck and your money. Let us know which method you decide upon and how it works out.
