Outer Limits 4x4 Board

hey guys a question..
what flanges are interchangable..
i know 1300 NT/WT/Late 1ltr are...
but will coily flanges go on a late 1ltr case or do i have to use WT flanges on a 1ltr case to run in my coily?

I think all the coiler flanges are different. (same bolt pattern, different seal depth)
