3.65" is the stock pulley size.

It is measured by the OD of the pulley.

ok, so the pulley i have is about 2.8 out side diameter... so i take it that its a smaller puelly...
There are no referance #'s on the pulley, and it looks like a plane pulley. I was thinking maybe its a UPR styel? any thoughts

I am pretty sure the 2.8 is made by Steeda. Indeed that is a smaller pulley.

if the car has a lower it will not have the steel cage on the front of the crank pulley.
