I'm using a thick aluminum sheet piece to shim up the B Pillar.
You can see our alignment is near perfect for the A pillar on the Driver's side.
Some surface rust will have to be removed on the roof underside before primering.
The fit of the A Pillar on the passenger side can be seen in this photo, just a little more adjustment and it will be great.
I noticed that the Coupe A Pillar is slightly different from the Targa A Pillar.
The Targa Pillar appears beefier.
Some slight modification will be needed to graft the two together to look great.
