Are these factory on a Blazer? (picture)

I have one on my truck between speedo line and tranny, to get my speedometer to read correctly.
But it appears I have one on the 72 Blazer
. Why would it be there if it is stock 350/th350? Were they all this way? Maybe not as stock as I thought?
Thanks

I never paid attention to the rhyme or reason on these. I've had some some and some w/o. I never paid attention to what ratios which ones had, but wondered if the standard ratio vehicles got none and this was used to compensate for the optional ratio
