['63GENIII]

Ok Eddy, I found the receipts. For the front hanger of the rear springs, I used an ORD GU28010 - 1 which is listed as a "shackle flip kit for 67-72 GM

For the rear of rear hangers, I used DIY 4x4 item #00590ka "first gen shackle flip and switch w/ 4.5" shackles."

I used the ORD up front and had to flip the spring front eye to the rear since the bigger eye on the front of the spring created a clearance issue with the hanger (which really wasn't sized to anchor the front of the spring anyway).

That said, I didn't know that the differences in frame widths that occurred throughout the years were compensated for by moving the hangers inward or outward so that the spring perches on the axles remained somewhat the same. I wasn't aware of this possible problem because the 2005 14BFF needed new spring perches anyway. Im guessing that you are trying to re use your existing spring perches so I would recommend taking some measurements. If you need measurements off of mine, I can get them tomorrow.
