Nice to see this project coming along. I don't know if you've mentioned it or not, but what colour is it going to be? Shame it's not a K, they had the best colours in the HK-G Monaro range IMO. Still, the HT did have some nice colours though.
Can't say i like the wheel choice though, i guess that's personal taste though.
Keep up the good work, will be a nice car to have when it's finished.
EDIT: Just noticed you said it's going to be seabring orange. Best colour for an HT, (especially if it's the original colour) my future father inlaw has an HG (well, the id tags say it's a G, but it's dressed up as a T) in seabring orange with the original houndstooth trim and a 383 Chev. Exactly the same from the outside as this car by the sounds of it (except it doesn't have the black stripes along the bottom of the car, only the ones on the bonnet and boot).
