Would this date code be correct for a 72 built in March of 1972? 5677649. The 6's may be 8's, Thanks

5677649 is a casting/part number; not a date code. My Corvette Parts and Illustration catalogue lists a 5677641 and 5677642, but that does not necessarily mean your 49 is incorrect. Your steering box might be an original.

You can check the '72 assembly instruction manual (AIM). The AIM has a diagram of how the steering box was mounted at the factory and lists the original part number.

The 75-82 boxes had a cast in Julian date code along with a stamped date tag on a cover bolt. The early 70's had a cast in "T" in a circle on the back,the C2's had a "A" in the circle.
The casting were the same from 63-79, the 80-82 were a little different. The 63 used blank iron cover, the 64-68 used the iron covers with "ADD LUBE" cast in, the 69-82 used an aluminum cover that was again different by 80. The gear ratios were all the same from 63-82, 16-1. The input spline changed in the 69 run, some say it was early vs late other said it was manual vs PS but by 1970 they all had the flat at 12 O'clock to mate with the rag joint on center.

OK I check the box this morning, and I do have the "T" cast in a circle, with a alum cover. So I guess it is correct for my vette. Thanks
