stock vacuum canisters?

[Down Yonder]

I have an 87 wag..stock..but, I'm wondering if the PO added a quart size vac resevoir to the top of the driver fender (in addition to the smaller cruze vac resevoir)....The ball resevoir has nothing connected to it so I'm wondering if that failed and the quart was added as the fix?

Bottom line question, anybody know if the quart size resevoir is a stock item or not. Trying to keep the vehicle a virgin.:D

Yes, it's stock. Probably plumbed to the cruise control.

[Down Yonder]

yes, one is plumbed to the cruze..but there is a second, larger one.
