yoke fitment

[cornishbob]

ok so i'm fiddling with a '62 a65 star.

does an a7/10 top yoke fit on it?

No they are different shapes.

See this early A65 top yoke on ebay.

i think youre missing the point of the question
i already know about the a65 ones and the a10 ones but do the holes line up? thats obvious
the '66 a65 top yoke isnt a dropped one and looks very similar to the a10 yoke

theyre all 6 3/4" (??) and the stem is the same diameter as far as i'm aware. its just the offset of the stem hole to the fork holes.

all it would take is a couple of lumps of billet and a lathe(or a cnc)  and the difference due to the a65 drop can be sorted.
