Last year of the O4B4 Intake manifold??

Hi
This is a question from a member on another board that has not been answered.
What was the last year Edelbrock produced the 04B4 intake manifold?
Thanks
Bernhard

Thanks for the link, dc2x4drvr. I have a O4B on my '68. It's the "middle" run. The first ones only had the Holley "square" bolt pattern & you had to use an adapter to mount a Q-jet. The middle run had the extra "meat" in the casting for a Q-jet but it still wasn't machined out for the Q-jet like the pic I put up. I was able to machine out the area to get my carb to mount without the adapter. I think they stopped making them in the mid seventies. The second pic was the last style made, it's what mine looks like after I machined it.
