a good thing to do in your position might be to try and find a truck where someone has already done the gas tank conversion, there are nice truck popping up on craigslist all the time. alot of people have put alot of love into them and just get in a pinch, so you can find one with updated discs up front, wiring, rear tank etc... i have an 18 month old and my truck is my daily driver, so trying to do repairs start to finish during his nap so i can get to work the next day has been pretty insane. sometimes he wakes up early and you gotta slap everything back together in a hurry! that was the thing where the book came in handy was knowing which mods would fit into your picture. my tank is behind the seat, which has given me no problems, i have heard people complain about gas fumes though. and i'd rather be in my truck than in the 06 scion i was driving when it comes CRUNCH time....
