Big Block K Frame Identification

$950 is more than triple its real world value and that one looks like one of the poorly built ones (many were really bad). I'll convert one for $200 plus shipping. Shipping is about $50 each way these days. If the k-member is dirty that also includes a day or two in my hot tank. I'm not looking for cores anymore because they are so hard to find, but when I come across one for a good price I will pick them up, which hasn't happened lately. Gone are the days where I could find a complete front end with discs, steering gear, and k-member for $50...
