HX 4.2L Sandmn ute is probably not a great car to throw bulk $ at especially if it isn't one easy to pick as a Sandman. A perfect restoration would probably struggle exceed $25k, possibly $20k and it'll cost you more than that to restore it. So my advice would be to fix it as best you can but don't try to do it as per original, just do the best you can and minimise spend on it.

Send me the car's ID plate details an dthe engine number and i'll see what I can find on it.

Yes HX Sandman had Lukey mirrors, they were black not painted like HZ.
