suburban 2nd &3rd seats
 

does anyone know the size of the 2nd &3rd seats and are the brackets smaller in front or rear. thankyou

The second and third seats are the same size. Same seat as the Blazer back seat also. If you need actual dimensions I'd have to go measure my burb seats.

I am not sure what you are asking as far as your brackets question . I'll tell you that the middle bench has longer front brackets(legs) than the back seat does.
