New Mancini Timing Cover Fitment Issue

Assuming the 1832 is 183.2mm and the 2153 is 215.3mm, that would be 7.21" and 8.48" respectively. That is a 1.27" difference on just that one measurement. I would get a refund from Mancini and buy a good used one.
I'm thinking it wasn't zeroed out. Look closely at the scale. The Mancini one looks to be close to 150mm, whereas the original looks to be maybe 146mm. Not sure what's up with the LCD display.
