Sorry for no reply, only got my phone at the moment (as my pc has thrown yet another wobbler) and the phone doesn't like the little pic you have to assemble to send pm's.
Will take some more pics and try to upload them to this thread today.
Sounds crude, but basically rather than cut the middle bit and rejoin it you cut.the end off the middle bit. This then allows you to lay the fiberglass trim from extreme over the whole pug doorcard. Then you lay maskingtape over the centre section where there is a gap between the fiberglass and the leather and build up a fill in piece. The resulting lines don't flow as well as the extreme method, but if you aren't too good at stitching then I think it looks much more professional.
