This is what mine looks like, but I wasn't sure if they added an o-ring to later models, so I wasn't going to question it. Lord knows the 4-eye stuff is always a little different, haha.
Well my dipstick is out of an '89, but then again the engine itself is out of god knows what before it was stroked. I'm almost certain that as far as 302s go, all the dipsticks are the same. The only differences would be if there was some kind of weird oil pan under it that changed the oil level somehow and then the stick itself would read different. Another thing could be how it attaches up by the header...but mine isn't bolted down at all...it's just jammed in there. I had to sort of custom bend the oil pan end after it was in the block to clear the windage tray, so it's not gonna slip out.
I tapped one and installed a threaded plug, since I had a 79 Mustang pan that has a dipstick fitting, so that would work also. Should not hurt if you put the dipstick in later.
Note that 302's have come with dipsticks in the timing cover, the oil pan and the block. I ended up with a late pan with no dipstick hole on and early block with no dipstick hole....for a while.
