OK, must be late HJ HOLDEN, Belmont or Kingswood. Probably HJ Kingswood to have forced air, but it isn't cutout from what I can tell. I'll look closer at it. I've been trying to remember where it came from, and from memory I think it was off my old HJ Kingswood ute which had a factory type 5 dash, it was a later HJ. I must have changed fascias at some stage, probably because of the holes - hassle is it has 3 x holes drilled on the textured section where an RTS badge would be on a HZ, the other damage is on a smooth section (radio cutout). Not sure if that textured bit is the same as a normal HJ-X dash and the whole bit could be plastic welded into this fascia. I'll see if it has a number on the fascia.
I also found the HZ SL/E burr walnut fascia whilst I was looking for it. It is mickey mouse, not even damaged as it had a factory radio. Still has the chrome on edge, and the clock is spot on. Instruments are floating around the shed somewhere too, but they are not from the SL/E but from an old HZ BO6 tonner I used to own. The HJ instruments of the fascia mentioned above are probably stashed somewhere too, I thought I'd found them when searching for the fascia but it was only an LH SLR dash from the SLR5000 I pulled apart a while back.
