I think that area (mounting boss?) for the oil filter is close to correct on the 1/25 Revell '68-9 Charger R/T kit.
One thing I noticed when looking over the parts last night is how the rearend is laid out and located among the other parts. It appears it's an insert, which leads me to speculate/predict a future variant with an 8-3/4" rear end is all but certain. I can even see a place for the (what would be molded separately) gear carrier (chunk/pig), so sign me up for an AAR in 2016.
Casey I trust we dont have to wait until 2016 before we seeing a `70 Cuda AAR spin-off from Revell. I hoping to see something like mid-2015 timeline.
