History Identity of this family car?

going through old slides I saw my great grandfather's car, these photos were developed in February 1968, I went through just about every year of every make from the 60's trying to find a match, I know ive seen one before but can't put my finger on it. It was difficult to get a good photo of it.

interestingly though I saw the car my grandfather (his son) had before he bought his 1969 torino, a gold amc rambler with mismatched tires.

for reference, the rear end of the first photo has 7 letters on the trunklid

 

Edit: 64 chevy 2

 

65-66 Rambler?

 

Looks Rambler to me, and it has the lay flat seats in it.

 

I think this is correct.

 

Looks kinda like a 65 Rambler.

 

This looks close

 

This one has the sharp upper rear window corner though

 

Yeah that has to be it, thanks. like father like son I guess

 

Better shot of the rear end. Yeah, that's definitely a '66 Rambler Rebel.

 

This is a '65-'66 Rambler 660.
