Here are the instructions to the Draw-Tite hitch for the Stinger:

You'd need to find out if the 4 mounting holes on each side are the same as on the G70. Even if they are the same, the fit around the stock Stinger mufflers are pretty tight, so they may not fit around the G70 mufflers, which are different.
Also, since this is not a "no cut" installation on the Stinger and required cutting a notch for the receiver to poke out, you'd be lucky if you could do the same on the G70.
Not to say it's entirely impossible, but unlike other bolt-on compatible Stinger/G70 accessories, this one is iffy.
