Torsion bar adjusting plate

Some years ago I made and had powder coated a pair of adjusting plates, and although they looked lovely I have noticed recently that they have started to 'bend forward' - at the top where they transfer the load to the horizontal top of the crossmember.
I have just taken them out for 'straightening' and decided that they weren't fully in the corner when the load of the spring was re applied.
However even though they were in the corner they have done it again!
I have now decided that the radius of the bend on the adjuster is too great, putting the torsion bar load away from the corner. A new pair arrived today with a nice tight corner bend which I am hoping will prevent a reoccurance.
Has anybody else had anything similar?

Maybe the top of the crossmember is beginning to crumble!

The lip on the top of the adjuster plate has to be a sharp bend. Iv'e seen DIY plates bend as you have described. Excessive radius at this bend will bend the plate.

Must be a massive force involved

Indeed - it's the full dynamic loading of the front end of the car! Only that little edge + clamping force of the bracket to the crossmember that opposes it all!

Offside one fitted and everything is staying in position with no bends yippee!, got to do the other side now, but I must say it's been apart so often I think I'm getting quite quick at it!

I've seen this too, but never really worried too much about it (yet). The locking bolt should be high tensile and done up FT.

Be very glad it comes apart easily! If it's had enough salt and not been apart for decades you would not believe how hard it can be to rebush and reset the front suspension!

Hear hear. And, for good measure, hear :D

Nearside now exchanged and it's all looking good!
When I held the old and new plated together there's not a great deal of difference but obviously enough to make them bend.
Thanks everyone.
