Well I stand corrected. I cannot see any reason why cast iron would be used in this way but it does explain why some members are having so much trouble removing old ones. It’s not very often I’ve needed to replace these. When I recently Refurbed my B1 I used a NOS swinging arm so didn’t need to remove them.
The one’s I am offering in brass are aftermarket parts and in my opinion that if nothing else is an upgrade.
Just for the record (9J) is October 1979, 1989, 1999 or 2009 as they changed the label style each decade and re-used the letter designating the year. The label on the part you have was used in 1979.
I’ve checked the prices today and they are at £30 posted for a pair.
Let me know if you need them.
