/6 K-Frame vs. V8 K

I need to know before i make an expensive purchase if the /6 K is the same as the V8 K in every aspect except position of mounts. I am transplanting a 383 into a 68 Dart with the / and would need to know if there are differences. If I can just put in some Shumacher mounts and convert, awesome, but if a V8 K has any dimensional or structural differences, can someone give me some feedback. Need to get some answers before 8 AM and can't find much about online. Thanks Guys!
