Need help finding a diecast/model car
 

My buddy and I build custom cars for the guys at work. So far we've done:

80's T/A hotwheel (custom paint, wheels)
70 Firebird johnny lightning(custom paint, wheels)
71 Monte Carlo jada(custom paint)
69 Nova hotweel (custom paint)
68 Camaro hotwheel (custom paint)
04 GTO prostreet 1/24 scale (custom paint, wheels, big block, roll cage, shifter, cowl, parachute)
70 Torino GT 1/18 scale (custom paint, louvers, double headlights)
Many more to come hopefully!

We have been looking for one car in particular for quite a while now. A 1975 Chevy Monza. I can't seem to find any at all, except a couple of hotwheels. That would be okay, but one of them is a redline and doesn't sell for less than around $25. Help me out guys! Everybody love a good recon mission and it doesn't get much more difficult than this. No time frame. When we get it done, we get it done. We don't tell the guys we're doing this until they see it on their desk one morning.
