I'm referring to the lingage on the carb itself. the 7037203 rochester is designated as an early style for use on california built camaros with a.i.r. and 4 speed trans. and is almost identical to the 7027203 which is non a.i.r.. The carb i bought is correct in every way, right down to the date code of A7 . The only thing missing is the outer part of the throttle lever which is the piece that the accelerator rod attaches to. the 7027202 and 7037202 are very similar carbs but are intended for automatic trans and the throttle lever is a one piece stamping as with most carbs with multiple holes for kickdown,cruise control etc. whereas the 4 speed carbs had a two piece throttle lever with the outer part attached with two slot head bolts. I did somemore research and found a picture of a 7027203 in CHEVROLET by the numbers by Aan Colvin and it clearly shows the two slot head bolts and a second pic on the next page shows a partial of the same lever and a part # is visible. I'm sure most people, including myself would and have looked at these carbs in the past and never even noticed that the lever was that way. I would really like a close up pic(s) of the lever showing the part# and the slot heads . I notice that you have a "67 ss/rs listed, I can email you a pic of my carb to compare if necessary. Thanks..
