3 bolt to 4 bolt swap, simple, dumb question

My question is, is this part the same between the 4 and 3 bolt diffs? Will the 4 bolt mount right up? Can I use the one currently bolted to my 3 bolt rear?

I reused mine in the swap and I only see one part number in CAPS for it so it looks like they used the same part from 90 to 94.

The one from your old 3-bolt setup will work just fine for the 4-bolt rearend. The only thing it does is bolt up to the rear diff cover with two bolts which are the same on both. If you have the diff, axles, and axle cups you're good to go.

I just unbolted my 3 bolt rear subframe and bolted in a 4 bolt rear subframe, it works fine.
