As the title states I'm working on a set of 426 Hemi Holley carbs (list 4235 and 4236) for my brothers 68 Hemi Dart and I'm trying to find what the original factory secondary plates were for these carbs. (as the carbs seems to have been messed with by a previous owner)

The secondary plates I have currently are both stamped with 34R-9716B (casting #) and
The Left 4236 is stamped with a number "6" which translates to a .070 main and a .026 idle
The Right 4235 is stamped with a number "39" which translates to a .073 main and a .029 idle..

I have a feeling these are not right or maybe they are.... I just want to make sure..
I'm not having much luck out on the internet and I'd figure I'd turn to the experts.

Thanks in advance for any help you may lend...
