8-1/4” will use 8-3/4” shock plates Dana will not and 7-1/4” plates only work on 7-1/4” axles in the Mopar line. I don’t count brand x manufacturers.
*Note* an 8-3/4” CAR shock plate also doesn’t care if if it’s A-B-E body they will all interchange from 62’ to 72’ 8-3/4”
*Also note* 62’ B body is the origin of this plate.
That’s all folks!
