broken shocker brackets

It is interesting all the talk about 'which shockers' to put on the 4by.
I have a HJ61 and have had both top shocker brackets on the front crack over the years.
Not too long after I bought the car 2nd hand (with Bilsteins attached) one of the brackets broke, leaving the shocker waving to everybody as we passed. It was successfully welded up by a local engineering firm.
A couple of years later I left the Stuart Hwy to travel the Plenty, and about 50 Kms later I heard a knock and it was the shocker bracket on the other side.
I went up to Tennant Creek and had it welded and the guy who welded it said he did 'plenty of Toyota with aftermarket shockers, they don't extend far enough and break the bracket'!!.
I am not into extreme or even 'fast' travel, still have the same shockers, no more problems.
I must say that I assume that the shockers on my vehicle were for this model.
The history of the car read very well when I bought it so no reason to doubt that the wrong shockers were fitted.
Just interested if anyone else has had problems like this, and possibly any link to non genuine shockers.
