As soon as I seen the 1st picture I knew this would be a cool rig, very nice, pity we don't get to see many 1:1 customs like this down under, our laws are retarded.
I'm doing Mad Max's interceptors and as the kit gauges are incorrect I found pictures on the net of 1:1 gauges and had them reduced to scale. To get perfect circles I use a punch tool from Micro Mark which has proved to be invaluable http://www.micromark.com/micro-punch-set,8603.html
They have to be the most detailed carbs I've ever seen, very cool.
Are you able to do the indicator lens that belong in the grill of the S & H Torino? If you could do them to suit the MCG photoetch set that would be awesome
