not that i know of, unless you cut and paste so to speak, fabrication= anything possible, i switched mine with a fiberglass version of the stock tank and now im kicking myself because the metal straps that hold it up are cutting into it. so i thibk im going back to stock.

i have heard of people adding a supplimental tank in the trunk to put extra fuel in, so when you run out you turn a valve and it dumps into the stock tank (which is big in rally so they dont stop)
