1990 5.0 HO Carb Conversion Dizzy Question

[Brownwood]

Converting a 1990 5.0 from EFI to carb for an engine swap. I went with a stock look Pertronix dizzy with steel gear to make life easy. The dizzy drops in fine and engages the oil pump but it is 1/2 inch shorter below the gear. Do I need a longer oil pump shaft and if so, where do i get one?

You try adjusting the locking clip on oil pump shaft
