B body width Dana or 9”
If I was planning a trip to visit my Brats in Phx in the near future.
From just one measurement and not lookin' for the tag to decipher, it appears to be from a '67-71 mid-size.
Right about 60". Unsure of internal condition, never opened it up. Spun without obnoxious noises when purchased.
California Central Coast.
