A great Mopar mystery (at least to me)

So I wanted to swap out my stock small block LA engine valve covers. The finned ones I had lying around, wouldn't fit under the power brake unit in my 62 Lancer (see virtually no room anywhere). It's an 8" unit. BTW, the breather holes on those are drivers side front, passenger side rear.

After and extensive search, I saw a pair of Spectre low rider covers that appeared to fit. I talked to the tech and he assured me the photo was a precise representation of the part. Part ordered, part received, uh it was a mirrored photo. It appears that all finned covers have breather holes, passenger side rear, drivers side front. All short, chrome covers have drivers side rear, passenger side front breather holes. I am at a mental impasse, causing more of a brain drain than I'm willing to invest.

Long story longer, I installed a set of chrome shorts and finally found a 90 degree PCV to fit under the power brake unit. Problem is although it works with engine not running, I wish to drive the car. With engine running above idle, the pressure tips out the PCV valve. It wasn't an exact fit, so I wrapped tape around it and such. PCV into rubber thingy (see brain drain), into valve cover. A good look, but not highly functional. Like some women I've dated.

So I'm hoping to see or at least hear the burning bush, ah burn. Any advice would be greatly appreciated. Actually maybe those goofy looking stock ones, don't look that goofy after all.

Thanks in advance.
