I am totally confused now. If I look at the 521 Restorations site they just sell the Spectra tanks and say the CR11E is good for '70. I'm ready to start cutting and welding. :eek:
Here's what I have ascertained about the tanks......
68 & 69........Filler hole too far forward no vent.
70........correct filler hole with no vent.
71........correct filler hole but with 4 vents.
72+......correct filler hole 1 vent.
Just plug the vent hole on the CR11E or use it as a bypass.
