Welcome
But I don't believe you till you post picks
Haha - My sinister way of forcing you to post pics so I can get my cobra fix.
You may wish to PM "Jethrow" he's seemingly working on an FFR and is WA also (yeah I know, its a small state).
Here is his thread for your interest.
Tim's Factory Five Mk4 Build Thread
I hope he doesn't mind me linking it, but I figured the two of you may be able to share ideas and experiences with your FFRs .
Best of luck with your build!
