Hey guys, I found a drive shaft in my shop (i forgot about.) If I remember correctly, its from a 1500 Suburban 4x4. The only part number I could find on it was 314719 or 314718. My drive shaft on 87 V20 3/4 ton Burb was shot so I was going to try and make this one work in the interim (fail.) Now I can't remember what it came from. Is there any way to identify it, length etc? Thank you in advance.
