+1 for Ricks... I've probably used at least a dozen of Rick's tanks.
Our Chevelle feature vehicle we just finished has a Rick's Stainless tank in it...

Sounds like you already have your tank in but for future reference having them trim the front corners of the tank are a big plus for adding 3" exhaust on over axle stuff.
The majority of the G.T. 500 E's I deal with have them as well. They do weigh a ton but for visual effect on a high end build I don't know how you would beat them.
Erratic senders have been an issue in the past. I jrecieved this tank from them yesterday with a new- new style sender I've never seen before so we'll see how this one works out!
