Here's a German page (I translated it) with the parts for the '70 Cabriolet:
It has just a swing axle but seems to be the padded dash I can use.
And here's the '68 hardtop kit from the same site:
Interesting it has the old non-padded dash but has the '68 engine lid with the hump. This one has no louvers and the '70 has them across the top. We should be able to get quite a few years out of these two kits.
Looks like I'll be getting a few of these too! Between the two kits, there are so many possibilities...
