Standard 45D points distributor for all pre-A+ 998s and 1098s. This is a stock replacement, but may be used with lightly modified engines. This distributor is fitted with a vacuum advance unit. 
 
If you are having trouble identifying your distributor, a pre-A+ uses two bolts and a hold down clamp, whereas an A+ uses a single bolt on a hold down fork.
 
Includes cap and rotor.
