K Frame

Kern Dog said
The front of B and E K members are curved like the one on the right. Yours is flat across the front. NOT an E body K member.

There is something strange going on. Measuring it and posting the findings may help but that curve I mentioned is a clue.

The weird thing about this one is the through frame sway bar provision, with biscuits style motor mounts, is why I was rather sure it was E body.

Is there any other places to find k frame info other than
K-Member ID Chart
