There isn't a consensus on any one particular fuse block. Have you searched the archives yet? In a case like this, I think you will get more info than you can absorb by doing a search for "fuse block on this board. There is a wealth of information there and a lot of pictures of the various installations.
If you still have more questions, we can certainly answer those as well.
I use the Buss 15600-06-20. It is available at Napa for about $13. Six fused circuts and I also add a 40amp relay from Napa for another $5. Mount it just in front of the OEM fuse panel for easy access. Drop me a PM with your email and I'll send you some pics with instructions.
