leaf spring hangers 67-72 vs 73+

I'm looking for a drop leaf spring hanger for my 68 GMC, it already has rear shackles and de-arched or custom leaf springs that were installed by the PO and is sitting at about 6" drop. id like to get about 1 more inch out of it.

so here is my question. aside from spring widths, do the 73+ drop hangers have the same frame bolt pattern as my 68.

I'm trying to do this relatively cheaply as i plan on doing a 4 link style rear suspension in the future.

I made custom front hangers. I used 73-87 front hangers. I cut the brackets, that would mount to the frame of a 73-87 and I used 1/4 inch steel to use as the mounting plate, then weld the rest of the hanger to the plate .

If you get a sticky tire the cal tracs will surprise you how hard they bite

Re: leaf spring hangers 67-72 vs 73+

Yes bolt pattern on the the frame is different. For my frame, there was like guides I would call them, for where the hanger would mount, the 73-87 hangers just straight up won’t fit a pre 72 frame.

Also said above is its 2.25 width and 73+ is 2.5.

Are you looking for a front hanger or ? Because I have these front hangers that I bought on eBay, and they never ended up working and I went the custom route.
