Hi!
Have someone heard about a 10 bolt 7" diff from GM or are all 7.5 or bigger.
A man says that this is a 7" diff.

 

Smile, nod your head politely, and don't argue; just go on about your business. Arguing would be a waste of time and oxygen. Unfortunately, some people are reality-proof.

Looks like an Eaton Gov-Lock for a 7.5".

Run away!!! You don't want it.

 

if i'm not mistaken i think there were 7" 10bolts or maybe 6.5"
trying to recall my 'ole Vega/Monza days
the H body had a weaker 10 bolt

and don't forget the vette, Chevette that is, i think those were 10 bolts, and smaller then 7.5"

not sure if that is what the guy was referring to, unless you meant in the F body model lines
all 10 bolts were 7.5" or larger (i'm pretty sure)

 

Ok Thanks

 

the vega's had 6.5's till 77 them went to 7.5's

 

you could always prove him right/wrong
