Oil dipstick and tube, and engine stamp decoding

[Dleslie212]

77 K10 with a 350 here. Previous owner installed some crappy chrome AutoZone oil dipstick tube on the drivers side that doesn’t fit properly - it spins and moves and pulls right out. Does anybody know the proper dipstick I should buy? Looking on LMC doesn’t show me anything at all, and everything on Summit looks completely different, I’m not sure which I should buy

Also, I wanted to see if anybody could help with a stamp decode. I found this on the passenger side front, just behind the alternator. Two sets of numbers

First - 014740C138
Second - V0801CKD

Thanks!!
