New here, just bought '90 ZR-1 - ZR-1 Net Registry Forums

The K brace is correct, three 13MM bolts on the P/S frame rail(one on the top is hard to see but easy to remove)........two 15MM in the front and the the one that attaches to the motor mount. This gives you access to the O2 sensor, harness but unscrewing it would have the same effect. This will not drop the engine if removed.....thanks to Jeffvette for the info last week,

I would assume that the lifting brackets are not required, not sure how a chain could not perform the same function.....but I will let others chime in on that.
