70 Charger b5blue seat questions

[b5blue]

Here's a pic of my new seat covers with my new seat back covers. With nothing left to go by is this even close?  (Will I need to dye the seat back covers to match?)  While this is far from a true "restoration" the darn seats are eating up cash and I never found a true b5blue headliner like I had some left of. So the seat backs "sort of" follow the darker blue of the two tone blue thing starting to go on inside.

The colored interiors did not have the same shade on everything when these cars were new. Here is an image of a blue interior in a low mile Challenger T/A, if I remember right it had about 14k on it. Note all the different shades of blue.
