Read Wheel drive
I did see a bunch of these mule cars next to my work in detroit. They where 300Ms with a very high suspension and rear wheel drive and dual exhaust from the 300C, Magnum. They also had a higher hood line because of the motor. It look weird the first time I got see one, it looked like the 300m had 4X4 suspension. Yes I know of the difference in wheel base, these cars did have some body work done because of the lenght. Dam, dam I wished I had a picture phone back then..dam dam
Basicly Imagine if you took the drive train from the 300C and welded on the body from the 300M, no these cars are not very compatible but then again chrysler did it.
