Hi guys,
I think the seats I have are a little taller in the back rest than others so I think they would go back further if the were shorter.
The rear of the back rest hits the rear deck.
They are a traditional Cobra Style seat but a bit taller to help with our UK registration regulations they also have detachable head rests.

I also had them heated while I was at it.
Sad I know, but I like to drive in the winter.
