SV 7/8" brake M/C plunger

It appears that I have an early SV Girling 7/8" brake cylinder that has a plunger where the seal goes on the PEDAL END of the plunger, as opposed to the newer SV M/C where the seal goes over the CYCLINDER END of the plunger. The big difference in the seals is that the newer model seal has a 10mm hole while the older one has a 14mm hole, allowing it to be stretched over the 7/8" end of the plunger. The current rebuild kit only contains the 10mm hole main seal which will not stretch over a 7/8" plunger end.

Looking for a seal with a 14mm hole or, failing that, a new style plunger with the small hole seal at the M/C end of the plunger?

With 2,600 miles on my Alpine thus far this year, I'm hoping to get a few more rides before the salt hits the road.

Have fun,
Jersey Alpine (Vlad)
