slant six dipstick

We dropped a late model 225 (1983 if im reading the casting right) in my girlfriends 72 scamp and its been about 2 years since we got the motor and I took it all apart to check, clean, and repaint it and now I dont remember where the damn dipstick goes!!!
Every pic and car I have see the dipstick is mounted in the little hole by the driverside motor mount, but on her motor there is no hole, the little pathway for it in the oil pan is there but there is no hole in the block.


Im going nuckin futts trying to figure this out, I even jacked up the motor and took off the motor mount to see if it was under it.

In the last pic you can see the little boss just to the right of the motor mount and there is no hole at all for the dipstick.
(we went with differant headers by the way)
