i am about to order a floor pan and i need the rear seet braces.do all full floor pans come with them?this is where the front of the rear springs bolt.

If your refering to the complete floor pan , yes it comes with the torque boxes and the rear underseat braces for the convertible. it does not come with the h brace in the center of the car.

I just bought this car it is a 1969 camaro it is not a convertible and it is very rusty it has to have all body panels.I also have 67 and i need to know if the subframe will work on my 69.

Yes
