Is this the correct brake booster for 1970 LS-6?
 

My brake booster is marked 9391 on the back and 076 in the front is this correct for my LS-6 Chevelle?
I have a used booster with 9884 or 0884 on back and 216 in the front what application is this for?
Thanks! John

Yes,that's the booster used on 1969-70 Big Block Chevelle/Elco with P/B.
That's showing a March 21st,1970 assembly date so if your LS-6 was assembled after that date,it would be considered correct too.
