If you look at the 72 dash the instrument cluster is a seperate plastic part and would also have to be changed with the 72 pad. 69 is all one padded part.
Here is whats suppose to be a 70 . Is that a pontiac emblem above the glove box ?

I can't seem to get the one photo of the outside of the car to download at TC but I can email it to anyone that wants it. Send me an email to walcan@cablerocket.com and I will email it back.
