Out of interest I did speak to Seven Workshop and apparently both types of toggle are investment castings which surprised me as I'd expected the 3-speed ones would have been laser cut or wire eroded from plate but this may explain why some people are reporting they can crack if bent.
Although it's a bit of a pain to do I think I'm going to have to try to alter the height of the pegs as, apart from anything else, I don't have access to oxy-propane or similar to do the heating.
What concerns me a bit is that having re-measured both the dimension of the toggle lever ends below the "bell housing" face and also the corresponding depth of the slots over the repair pegs there doesn't seem to be much correlation. I numbered the toggles 1-3 just for reference and have found:
Toggle 1 - Depth below bell housing = 4.88mm Depth of slot over peg = 7.19mm
Toggle 2 - Depth below bell housing = 5.91mm Depth of slot over peg = 7.12mm
Toggle 3 - Depth below bell housing = 6.72mm Depth of slot over peg = 7.46mm
I have tried to determine the theoretical amount to take off each peg to compensate for the varying depths each toggle is below the bell housing which is dependent upon the ratio built into the toggles but haven't been able to get this to work.
I guess I'll just have to reduce the height of the pegs for toggles 1 & 2 so that they are all the same as toggle 3 and hope this brings all three toggles to the same dimension below the bell housing but I'm not that confident.
