Hi guys!

Well I managed to fix that small "hiccup".. in the end I decided to erase de edges, change the "keep faces together" option and re-extruded the edges.

It seems to have worked fine, baring odd vertices that don't seem to want to keep together... but no worries... I'm happy with whats accomplished...

Thanks gster123, sspikedudley and oldhippie_tom for all the help and advice. Hope to repay you some day...
