Ok, my 67 frame was bent so I purchased a 71 donor truck for the frame. Once I started comparing the two frames I noticed some differences. Attached is a picture with four differences I found:
1- I believe is a bracket for the automatic transmission linkage
2- I have no idea
3- I believe is a helper spring but never seen one like this
4- Is this a factory rear bumper?

Can anyone confirm my assumptions. Thanks
