Umm, all 3Bs and RRs AFAIK had this. Even late 1992 S2 3Bs had it from the 
factory. Plus the brand new distributors with metal gears still come with 
them attached, so who's right? ;)

Nope, I don't think it will be dropped, as don't forget there have been 
quite a lot of 200q20v's sold in Europe between 1989 and 1991 and about 
3500 3B S2s as well between 1990 and 1992.

Lol, agreed with Bernie on this one, though a little preventative 
maintenance before performance upgrades doesn't hurt and spares pulling 
one's hair off wondering "WTF isn't it going right?"...
