Series 3 LI Special Headset

Hi forumgoers, I am new to this forum so bear with me please. I recently brought a 1965 125Li Special, I soon noticed that all was not right on the handlebars and the lefthand side gear change had excessive play, anyhow to cut a long story short after stripping down the headset it became aparent that the lower headset casting had cracked and was infact in 2 pieces being held together by the assembly and cables only
so I removed the headset from the scoot, stripped out all of the internals and sent it off to be Tig welded. When the headset came back from welding I was more than happy, the finish was great and the component seemed to be strong too ... until today when it broke again just to one side of the weld.
My question is this: I am unsure that I wish to keep repairing it, especially if it is going to keep craking again shortly after, it could be nasty if out on the road
. The price of the few 2nd hand units around is unreal to be honest, but the standard Li headset is a cheaper option ...
Can I fit a standard round headlight Li headset to my 'special' or am I going to have to rob my grandmother for the £175 for the 'special' lower headset ?
Many Thanks
Andy
