I asked them if it would fit and they said not . this was the reply .
I am sorry but the early and later brush plates are not compatible. The 220552 will be placed onto backorder however the lead time from our supplier is usually around 12 weeks.
There are 2 versions of this dynamo, the early one has a small spring at the commutator end with a 1/2” bore, the later version has a much larger spring, about 1” in diameter. The armature, brush plate and commutator bearing are also different.
