Differential bracket issues Superformance early Mod. 100's

[Moto Guru]

By the way, Took out the entire bracket today. It crumbles if you bend it by hand. No-one every did anything to it, no modifications no tinkering anything at all there. Paint weld everything original.
1. SP F*cked up on that weld and metal choice. (weld is not continuous, spot welded only). Don't get me wrong nothing else wrong with it, still keeping it (car). But it's a f-up there in the manufacturing.
2. Metal is somehow crystallized, breaks easily. hand strength (not back and forward, single bend break).
3. Bracket was manufactured with 3 pieces of steel, with their 45 degree angles, but only 2 spot welds on one of 45 degree sides.
4. tested driver side (solid) no issues. Welded continuously, good and Not crystallized in any way. alloy is good/solid. (still going to re-enforce it from below).

thank you.
Have a great day.
