When I pulled the golds off my 360 (motor came to me already put together), I found 3 that looked like this. Pretty sure I got my new ones from Smith Bros, along with the new pushrods.
I got sets from Smith Brother's.
I also have 3-4 sets unused from Crane Sets since I bought push rods and adjusters for. The get go.
They are with my extra set of 1.6 ratio rockers I have as a spare set.
I just have to find um.
