Just restore this one with what you have and learn. Then sell it and use that money to do the 69. I restored a 69 Camaro, Hugger orange, small block, it took me 3 years and 25 grand later and it was perfect. Some tips:
clean the rust, replace floor pans, clean the motor (maybe even repaint) you will be surprised at how much a decent paint job. You should be able to find somebody to buy it for a decent price, then use that money to buy the 69 Camaro. If you just want the car, research you will be surprised you just might find one that only needs little work.
