Anyone know if there's any difference between the 73-87 and 89-91 leaf springs? I know the fronts used different sized bushings and bolts. There's several listings online for suburban 73-87 v1500 rear leafs, 69 - 88 blazer/jimmy rear leaves etc. Looking for stock replacements for the rear of my 89 Jimmy.

73-87 vs. 89-91 Rear Leaf Springs

Other than the number of leafs and pack thickness for these, they look to be the exact same, except one is 130$ and the other is 390$. not sure what makes one 200$ more than the other
The main difference is the Teflon spacers between the leafs in the last few years of the squarebody lineup. There are 4 sets of 56" springs on this pallet.
1. 1973 C10 with a leaf or two removed.
2. 1982 K20 pickup
3. 1993 G30 van
4. 1990 K20 Suburban
56"? Or 52"?
Metric size bushings also come in to play on the rear .
If that's the case, I guess I'll have to shell out the extra $400 for the pair. I made the mistake of ordering 73-87 springs for the front and didn't realize the difference until it was time to install them.
Can't you just change the bolts? I thought everything was the same except bolt size
The bushings and bolt sleeves for the springs are different sizes
problem solved here . and cheeper than the 400 bucks extra .

That's real helpful sweetk thanks for that. Now I just gotta make sure that if I get the less expensive springs, that the bushing size I'd order off of ORD matches the springs I get. Odds are the 73-87 springs will match up with the 73-87 bushings, just don't want to get the springs and the eyelets end up being different sizes OR they won't fit on the 89-91 frameproblem solved here . and cheeper than the 400 bucks extra .

call them and chat . they will know a lot more than you think . 
but aftermarket springs need to be in hand first before ordering bushings as they can be all over the place .
