Has anyone successfully used the USCartool A500 Crossmember?

I trimmed down the long rib to be a bit narrower going to the rear on the transmission tailshaft, and also on the other side I trimmed some protruding parts off the transmission.
You need to reweld/reinforce the upper part of the crossmember again, otherwise the entire crossmember will slowly start tearing apart the spotwelds from the floorboards over time. Ask me how I know.
I had to lay a full weld on front and rear of the crossmember to fully secure it to the floorboards.
