'57 3-Spd Main Case Casting No. Puzzle
I was perusing Craig's List auto parts for sale for Los Angeles yesterday and found a '57 Corvette 3-spd listed with a main case casting number which has me puzzled. Using Alan Colvin's books as my reference, the tailshaft housing casting no. and cast date are correct for a '57, but nothing else is. The first three digits of the main case casting number are difficult to make out clearly in the photo the seller posted but the last four digits are very clear. Here is the casting no. as I see it, but the 1st three digits are somewhat of a guess: 3820210. This casting no. does not appear in any of Alan Colvin's books (I have all four) for a Saginaw 3-spd main case. Can anyone identify this main case? By the way the casting date code on the main case is D26.
