Subframe i.d. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

We'll, on round 2 I finally have a bare frame (almost) ready for blasting/coating. Now that I have all front suspension components off and can see all the numbers, I need a good source to verify my casting numbers and positively I.D. My subframe. I am fairly confident it is a 2nd Gen, but know there still are differences in ball joints, etc. A couple of the #'s I have are:
371675 K1 L10 8D and 371676 K1 A12 8D on the spindles
3964881GMT 70B on the pitman arm
K B29L and K1 6B9R on the upper control arms

Anyone know a good source? Thanks, Jim
