69 frame rail question

[Crider]

I'm working on a 69 satellite, very rusty. I've ordered all new floors and trunk pan, but the rear rails are also rusty. Besides 68-70 Plymouth, and coronet, what other frame rails were the same? Charger? 66-67 b-body? Anyone ever use goodmark rear rails? If so are they a good fit and the same thickness as original? Thanks for any help

68-70 B are the same including Charger.
66-7 are the same rail but have different provisions for the fuel tank straps.
I've seen 66-7 frames used in 68-70 cars.
Here are some 67 frames.

Thanks! I thought the 66-67 rails were the same, but it's been a long time since I last worked on one these and didn't remember for sure. Are you looking to sell that pair of rails?

I am. Actually I think I have 2 sets. Both are broke down to just the rails.
