When i was asking about using the rear 12r5.2 clip and mount it to the 12r5 chassis that just has the transverse battery position. I wasnt asking about an after market or other company to make the rear pod I was talking about using all associated parts bought seperately.
Wondering if its a direct fit.
The only thing I cant know for sure is the shock location. It looks like the shock is more forward on the 12r5.2. I wonder if it would be just redrilling the hole were the shock ball stud mounts to the rear pod plate.

Not sure if all other geometry is correct also.
