455 HO with AC oil dipstick

Hello guys,

The oil dipstick on my GTO got stolen, I'm looking to get a replacement but I'm confused of the length issue.

The care has Factory AC, I can't seem to find the correct dipstick length.

Anyone knows what is the oil dipstick length for a 1972 Pontiac GTO 455 HO with Factory AC engine?

Thanks guys. Cheers!!
Tony
