OK, let me rephrase: how much difference is there between a 69 Carter Qjet and a 67 Rochester Qjet? The accelerator rod pin is a little too big for the Carter I have on my otherwise stock 67. I can drill that out. On the choke side - any differences?

Finally, it would really help to know where the accelerator return spring anchors. I can't tell from any diagrams I've seen. Is it a bolt-on bracket?

Thanks!
