What to do, what to do? Rear lift question

I have a terrible memory, but aren't all 73-87 rear springs 56" regardless of tonnage? 67-72 rears are all 52.

That's why front lift spring kits with rear blocks are all the same for 67-87, but a full lift kit including rear springs is a different part number from 72-73.

Nope, most 1/2 tons use 52" rears for '73-'87. Also, I could have swore '67-'72 front springs were a little shorter than '73 and up. I could be wrong though.
