Little bit more progress, again this is really just for anyone who is interested
Taking aaaaaaaages but as I think I've mentioned it's a fairly small job for the shop and I told them not rush, so I'm not disappointed with the timeframe.
Anyways here we have the vent modified to fit and the bonnet under primer. The louvered section is curved more than it was in the pics above so as to clear the front of the motor.
Nat (owner of the panel shop) measuring from the cross member to the bonnet. It wasn't quite sitting flush behind driver side headlight, wasn't fouling on anything so trying to work out where the problem is.
Everything checked out so some gentle massaging in order. No idea why, I suppose these things happen when you're dealing with second hand bonnnet going on a 20yr old car... The sheet alloy is very thin too so may have warped slightly when the frame for the duct was being welded in.
Ok and one last shot with everything lined up nicely.
Still far from finished, still gotta chop & fill a fair bit, then get some mesh in behind the ducts. Hoping to get it to the stage where the bottom is painted and the mesh is in, high fill, install (and adjust anything needed), then block it back a final time with it on the car. I've got different front and rear bars to go on too so will aim to get the lot painted at once and blended through the guards and doors nicely.
Long project but paying off and hands down the nicest bonnet I've seen on a Z32 to date.
