Rear leaf spring swap

I own a 1991 B2600i, 4x4, 116k. I recently bought it used for $550. it needed a clutch, but with the low miles I thought it'd be well worth it.After doing the clutch I found that the leafs were broken on the rear drivers side. My question is this:

Are the leaf springs the same in a 2wd B2600 as the springs in my 4wd B2600?

Thank you,
