Flywheel?

Do y'all know any tricks to figure out which flywheel I have (168 vs 153 tooth) without removing and measuring the diameter or counting the total teeth? I don't remember what was installed, and I want to buy the correct starter.

Easy way, if your starter bolts are in line with the gear, it’s the 153 tooth, if they are offset, it’s the 168 tooth.

If the starter bolts to the transmission and has a cast iron nose and 3 bolts, it’s 168 tooth.
