Thats cool.
That spot where your cup is open closer to the bushing is where I was talking about T metal is thin/narrow in that area. Would hate to see it bend or even worse fail alltogether.
Have you considered a frame Z?
I just compleated one and it really is not hard to do. Has many advantages over what you are doing here. You are going to find that your lower arms are going to be dragging scraping all the time. With a Z you avoid this plus you raise your trans, exhaust and you can even center the wheel if you want.
Plus your not cutting suspention parts which should awalys be avoided.
Just a little advice from someone whos been there.
