I don't really have a step by step, but someone asked me the same question a while back and I took some pics of it off the bike (first three are on the bike). It's something I cobbled up one Saturday afternoon. This mount is highly adjustable and I'd think it's probably work for about and pack you wanted to mount. I used solid steel for the whole thing (I covered most of it with leather for looks), and used grade 8 nuts and bolts for not only tinsel, but sheer strength as well. It'll hold some serious weight! I've probably had as much as 30lbs in it at times (bag of dog food, cat food, milk, etc.), so it's a pretty sturdy setup. Here's a link to the pics: Tour Pack pictures by pcarrell - PhotobucketI need a step by step on how you placed that luggage rack on the back. NICE.
