Looking for a distributor for my 2600i I found that the two different types are available. I know the efi on these can be finicky, so I wanted to know if there would be a difference between the two in my truck. I ask because I assume larger manufacturers will get the plans for a part, and just design both types because a lot of brands do this for a lot of cars. Just don't wanna get a new part that doesn't work because they saved money on r&d. Maybe I should just go reman?
