Hi - I'm new here and will be looking for a 70 Javelin or AMX soon. I've owned three 1970 LT-1 Corvettes and one 1970 W-30 442 and am saving the best for last. Not sure where to look for block/transmission numbers to verify matching numbers and don't understand how the car had to be ordered to get the center functional hood scoop. Lastly, are the two round vents on the front dash over the radio A/C vents ?I noticed in pictures some have them and some don't. Any other tips would be greatly appreciated. Thanks
