1969 vs 1970 Rochester 2G carb difference?

Thinking about buying one of the $100 replacement carbs on Amazon for my 307 powered '69 C10. But they all so for '70 and up. Any real difference between the 69 and 70 carbs that would make this more difficult than a bolt on?

I've been through this carb a couple of times and the accelerator pump well has issues and for a C-note if it improves driveablity until I get the 427 swapped in, I'm good with that.

The one on my 71 C-20 with 307 is acting up also. An older gentleman who has been rebuilding carbs for decades told me these are quite difficult to overhaul properly. I priced a kit from NSPA, almost $50.00 . Seems a hundred is a deal.

I used a kit from Mike's for $25. He also has a bunch of youtube videos that were very helpful.
