Is there a difference in the length of Wings between Series2A and Series 3 ?

Between Defender and Series?

1170mm = 117cm = 46"

I need a wing that is 50", 4" more length needed behind Wheel Arch to Bulk Head.

I have a '64 , 109" body on a 1999 Disco 2 frame.
The guy that did it cut a section out of the body behind the rear doors but only made the wheel base 96" instead of 100" to match the Disco 2 wheel base ???

I have decided the easiest why is to extend the bulk head 4" towards the front.

The wings are the same except for the side panel cutout between series and Defender.

I have decided that the easiest method will be to extend the bulk head 4" forward
