I would like to find a 3259 Holley with a late 64 or very early 65 date code. My car was completed Feburary 8, 1965 so nothing later than Janaury 1965. Either 513 or 4B1 would work. (First letter is the Year, the second letter is the month, 1 is January and B is December, third is the week of production). I have a 3259 dated January of 67 that will be available when I find the correct carb for my car. Thanks Bill
