When did they stop using a metal canisters for vacuum trunk release in a cutlass/442. Are the parts for a 1967 and 1968 the same? On the metal canister the nipple area is loose....is it supposed to be? Can it be tightened? Will it do any harm to put air into it to test it?

Thanks

 

I believe the last year for the tuna cans was 1968. I picked a few of them off of '68 A-bodies in junk yards years ago. My '69 has the plastic reservoir and I'm pretty sure that's the first model year they started using them.

The nipple on the metal cannister shouldn't be loose - that could be a cause for loss of vacuum.

Others can answer the rest of the questions.

It should cause no (more) harm to test the vacuum can. If it does leak one solution, besides getting a good one, is use a small dab of rubberized caulk? It comes in white & black & would be hard to notice once repaired. Like Randy said, I "think" the last year for the metal can was '68? They also used the same can for AC cars & on big cars & on other models & years of G.M. cars with AC.

 

I have had several 65 Olds cars with the metal can and never seen a metal one on a 66 or newer. I have several of either if you end up needing one.

I have a 65 442 with A/C and a vacuum trunk opener with both plastic tanks. Lansing built car.

 

I also parted a 67 442 with the metal tank, that was a Freemont built car. Maybe it was determined where it was built?

 

Back in the 80s, the first vacuum-operated trunk release I from a junk yard car came from a '68 Cutlass and it had the metal "tuna fish can" vacuum reservoir. I don't know where that car was built.

Starting with model year '69, I've never seen a GM car with the firewall-mounted vacuum reservoir. However, the power-door-lock vacuum canister in '69 was still a metal can, albeit much larger than the firewall-mounted metal vacuum reservoirs.

My '68 Cutlass built 04/30/1968 in Lansing has the plastic vac tank (on the firewall) for the trunk release, not the metal 'tuna can'. I'm positive it's original due to it having undercoat splatter consistent with the surrounding area.

Maybe switchover was late '68 production ?

 

I have a very original and dirty plastic tank on the firewall of my 67 for AC controls. I believe the can is the same part number as the vacuum trunk can.
