David,
Wrinkle finish needs to be put on thick and consistently to get a good finish. It's hard to do on large flat areas and you can often see the pattern you sprayed it in once it goes off. Mines wrinkled nicely but there are a few lines you can see where I sprayed it. it's only temporary till I can get it covered in leather any way.
You can use the regular Barina column shroud, you just have to trim that back lip off it that back lip off it that stands up at 90 degrees. Spray it with the wringkle finish paint to and it'll come up a treat.
The dash panel itself needs a bit of surgery to clear the column mounts and the key mechanism. you will need to trim a bit of the fiberglass inside that pocket where the column shrouds sits into.
I re did the dash mounts as I wasn't happy with Ians original design (surprise, surprise Mike re-invents the wheel again). I didn't like the fact that you have to reach in the back to undo the bolts (I hate stuff that's hard to work on). Also Ian's mounts were in the way with my guage layout using the big 2 5/8" guages.
I machined up 4 standoffs that bolt to tabs I welded to the dash hoop. I then bolt through the dash with some fancy machined up aluminium washers and stainless cap screws.
I also re did the column mount as it wasn't in the right spot to keep the dash snugged up against the under side of the body. I trimmed the top of the dash to make it a close fit under there. I raised it up about 10mm which gives me a little more leg room under the steering wheel.
Here's a pic that shows the dash with the suzuki shroud on the column.
Cheers
