Super Jet Case Question

OK so I had a 62T case with 61x cylinder. Recently I cracked the bottom half of my case (underneath the motor). A friend gave me his 61x motor but it has a different intake. So here's my question:

Are the bottom halves of the cases the same?

I haven't pulled them apart yet but they look the same, it's the top halves that look different with the different intake. I would love to bolt the 62t top half of my case to the bottom half of his 61x case. I've looked for part numbers but they all have both halves the same part number which makes me think it probably won't work.
