When using the dorman pieces do they slide in the factory tubes pretty good or did you have to use something to ensure they stay together?

I thought to myself what do they connect to elbow on the Z/28?
So I looked for pictures of the engine bay. I found the PCV tube and although I could not find the part number for it online I sent an e-mail to my friendly parts manager at Rodger’s Chevrolet (aka Maureen) with a picture of it and she found the part number for me. Fairly inexpensive (<$30). So I used the following 3 parts to route my PCV line in order to maintain the quick connects that the factory uses:
1. Stock 1LE Oil Separator tube cut down near the point shown by the blue line (Photo 1). This part is not available separately from GM and it is only available with the full 1LE Oil Separator kit (GM Part# 12653073). I was fortunate enough to find a member on here that sold me just the tube from their kit so I didn’t have to cut my stock one incase I ever need to revert back to stock.
2. Z/28 PCV tube - GM Part# 12653645 also cut down as shown by the blue line (Photo 2)
3. Dorman PCV elbow (Photo 3) found in Dorman Part number 46024 to connect the two GM PCV tubes together.
I also rotated the 1LE oil separator tube to the inside of the Oil Separator can to put the connection points closer together.
Well enough babbling here are the photos.
