Making a gas tank skid....

I found this one on the net

http://wrangler.kicks-ass.net/GasSkid.htm

looks pretty awesome, but says its for a YJ with a 20 gallon tank

anyone just happen to know by some chance if this is still gonna fit up without *major* changes?, of course with different mounting holes

i dont see any glaring reasons why it wouldnt, just thought id ask before i went and overlooked something blatant

thanks all

I don't see any real problems, but does the front attach with just the hanging bolts that hold the tank up (like Tomken's)?
