Update - I have found that the 4761 carb is matched with the 4758 to make up a matched pair for use on the 426 hemi. Now, all I have to do is find someone to would like to buy one or two.

The 70 Hurst is shown as using 4739 or 4741 w/AC. In different California. it's 4738 or 4740 w/AC That gets us into the range questioned, as the numbers get higher as they produce each different carb.

Not sure that makes sense as the normal convention as I understood it was H7 would have been a manufacture date of August 1967 and H8 would have been August 1968 - but most of the 67/68 Chrysler Carters were 43xx and 44xx series - possibly aftermarket?
