Hello, yes I did use the OEM trim panel, BUT ..... we re-welded the roll bar heated it and bent it to really hug the rear bulkhead. Here is my photo album of the work involved. Feel free to ask any questions https://www.flickr.com/photos/905823...57679633234944 I do have the fibreglass rear bulkhead that autoform supplies but it has no storage cupboard or top storage pouch. I wanted to keep both items so modified the roll bar to allow this. Cheers Mark.
