Don't be scared to gut the distributor of it's internal coil, and chop off that tall high voltage stack.
(The most important thing when buying a FWD distributor to fit a 50mm CAS disc is to make sure it has an internal coil. The internal coil one is what you want.)
Im gonna use the 50mm AEM disc in the VE Dizzy , Cutting off things doesnt sound healthy if one doesnt know what to do lol, i have room so ill just leave the dizzy cover n stuff, ill be running AEM Pencil coils.
