I bought a 67 elcomino and I am trying to find the ID numbers on the rearend housing. Any ideas where they are at on the housing would be great so I dont have to look so hard cause the housing is covered in 40yrs. of crap. Thanks

Passenger side tube front to top quarter within 6-8" of the center section. Wire brush it off clean and you should see it.

What's an elcomino?
