HELP Suntour Gear lever's don't fit??? UPDATE

[stringfellow1946]

Has anyone had problems fitting with Suntour indexed gear levers onto the standard brazed on gearlever boss?
The problem I’m having is that the part of the gear lever that fits (slips over) the two flats on the boss seem to be to small or that the boss is too big!
I have tried the part on some brand new bosses that have never been used & it doesn’t fit on those either. Its like it's made for a different size boss.
The only way I can see to fit it, is to file the boss down on both sides of the flat & the curved ends as well.
I originally thought it was because it had been Chromed (the frame is an ESA Colnago) but being as it doesn't fit to a new unused boss either it can't be that.
Did Suntour make different Down Tube Levers for different sized bosses? because I always thought that the gear lever bosses were all a standard size?
Any help or advice would be much appreciated.
I have fitted these lever's before to Buckler Colnago frames OK once the paint had been removed from the boss.

Suntour were a real pain at times because they went off on their own little tangent. Thin chains and the gear hanger stop size are two things that spring to mind. If they don't fit on a brand new boss then its the levers.

Are the levers from a band on?

Shimano made a different boss for a couple of years but quickly stepped back into line.

Not Band on as far as I know Shaun. They are brand new Superbe Pro Accushift SL-lP00-B or thats the box they came in.

I've now got to the bottom of the problem.
It was the gear lever bosses oversize I bought another set of NOS levers & they didn't fit either.
So I the decided to strip another Superbe Pro lever off my other Team Buckler Master & try that on the frame & that didn't fit either but the NOS ones fitted to the Master OK.
So I set to work with a file an after about an Hour finally got both gear levers to fit the ESA mexico.
NB I think it might have been because they were chromed?
