Love your shackle flip! How did you make those diff covers???
I"ll post some pics in the morning.
The skin is 1 piece of 1/2" steel with 4 cut outs to allow me to form the required shape.
A plasma cut flange was cut to the Diff cover bolt surface profile and the skin continually adjusted in a press until it fit the flange. At this point it was all welded inside and out.
Next a block was welded to the exterior face so I could hold it securely in a vice.
Seal surface was then machined in a mill to be truly flat.
Next the holes were transfer punched from a pattern made from the original cover.
Bolt holes were drilled from the flange side with an extended end mill to stay straight when they broke through the contoured side.
A jig tool was then used to line up the holes for counter boring from the outside surface, deep enough to protect the bolt heads.
Drill and tap for fill hole.
Grind and sand smooth to look like it was stamped.
Finally sandblast and paint.
Only silicone to seal.
Install and not worry about damage...lol
