Rear end markings

Recommended Posts

Just thought I would share this. My car was ziebarted when new. Anyhow while I was looking for the rear end ratio I came across the number 42 painted on rear end. I am guessing that it is factory because I had to scrape off the undercoating to see it. There was also a X in white kinda marking it off. Going across the #42.  The rear is a 307 ratio. 

 

Just wanted to share it. 

 

Thanks

The "X" marking is STAMPED NOT WRITTEN if the diff. is POSI. An easy way to tell a POSI from a glance is the POSI has a 3/4" square to check the fluid. Whereas the non posi has a 3/8" square you install the end of a 3/8" extension into to check the fluid.
