I lengthen the shaft with an additional piece. I actually will weld it on and the shape the new slot/tab myself to the correct angle. Then I'll tack weld the linkage lever on. If need be I make a new thottle stop.
If you host it I'll send you a comparison picture of one I did last week.
gimme an email.
