Is this a lift kit?

[C3pilot]

Tying to figure out if this an after market lift or some home made back job? Just picked up this ‘71 k10 that needs a total restore. It looks like it might have a 2’’ litt on it. Can y’all take a look at the brackets to see if it’s hard some sort of aftermarket crossmember? Does it look like the engine mounts have been altered too? Looks like it’s sitting low in the frame.

Any pics of what an original (cross member engine mounts) looks like installed would be awesome!
