Will a 1970 Dodge Dart Grill fit in a 1971 Plymouth Valiant?

I have a ROTTEN 1970 Dodge Dart I bought for parts, the grill is PERFECT though. I want to swap with my 1971 Plymouth Valiant drag car. I already own both cars, so getting a 70 Dart grill is easy as undoing a few bolts, but Will it fit on my Drag car?
