I noticed that the rear shocks can be mounted on either side of the rear a-arms and that the rear a-arms appear in stock form to be swept forward, so I removed the rear a-arms and found that when lined up and reversed the rear hubs do not line up.
Unfortunately I did not take measurements before the swap, so I can not say for sure, but it I did take one after and it appears that reversing the rear a-arms extends the wheelbase by 1/8 of an inch.
I could be wrong on this, but it may be worth a second set of eyes.
