@micman Most of the images in the books are three quarter views.
I think some of the counters for GDW's Brilliant Lances and Battle Rider would proxy well:

In fact, there's a whole thread on BGG:
Spaceship games with counters I use for playing Full Thrust

From whence I followed the links and got right to images, instead of sifting and downloading files, assuming you can size-and-crop til your heart's content.
I do believe I've seen counters OF GZG ships, but I'm not finding any currently.
I've always felt the Full Thrust rules were a method of promoting the miniatures, so the idea of creating a full line of counters doesn't exactly fit the business model. ;->=
Jon's incredibly lassez faire, but he IS running a business.
@agrippa Dull grey, but that adds to the 'proxy' factor, and the quartered counters ARE appropriate to original FTII, though not 2.5; if only they had twelve points around the edge
