Factory Correct Trunk Jack - info needed

[BuickGS65]

I'm looking for information on the CORRECT factory trunk jack for 1965.

There are SO many different GM bases, jack hooks, etc. - I'd like to know which one is 100% factory correct.

Can anyone share photos, dimensions and markings of a 100%-known-to-be-correct trunk jack, stand, base and hook?

Thank you!

There were three different makers of jacks! I have done some research, but never able to determine whether or not if they were used by all plants or certain ones!? Or when!?  The makers were,auto specialties,universal tool and stamping, and California jack co! I know one of the designs is a solid T shape , second one was a hollow almost square, third one is either hollow or a solid Y shape!? I will  see if I can find my notes! First picture is of two of the three correct bases, second is of the T style which is 34 inches tall ! Big car jacks can be used to lift the car but they don't fit in the cradle in the trunk as they are to long!

I have had another style different base than those 3 pictured. Another one was a longer T style base.  I think I sold 2 of that style years ago with hack assemblies.  I don't have the old pictures of them.

Great info - thank you! I believe I have the correct jack hook and pole.

Questions:

My mechanism is damaged, right? If so, does anyone have a spare mechanism?

Also, I'm missing the base.  Does anyone have the correct base for this jack?

So I found a picture of the base of the Jack 197064buick spec was talking about!? This one would be a Y shaped solid one similar to the solid T one!
I also found some notes ! Keep in mind most of the cars I have owned/parted
Were and are  Flint or Kansas cars! With a few Freemount and Baltimore ones!
So what I have found in the trunks may or may not be different that what came in your car! The 65's that I have owned had build dates from October 1964 to August of 1965! Some of the early cars had the Y style jack in them!
Also a few 64's I parted did! The Jack I found in most cars or most common was the one pictured in the previous post! Next would be the hollow style! I parted  20 or so cars,most were GS cars also if that makes and difference!?

Buick GS65 I would try and find a Jack and correct base  to replace the damaged one, mechanisms are challenge to replace! There were two types of wing nuts to hold down the Jack base and spare tire ! First hook was a small tread size with a stamped steel wing nut! Second style was a bigger tread size hook with a cast wing nut! I have pics and sizes somewhere! Also if car was equipped with road wheels from the factory the lug wrench would be big car 13/16 hex to fit the acorn lug nuts! I haven't found any differences in the board that covered the spare tire! The hold down cap would need to match the the hook in tread size!

My jack is missing the spring that is in the mechanism Dan shows in his pictures. Everything else is in excellent shape. Does anyone sell that spring? I?ve searched around, but not much luck. Does anyone have a picture of the spring?

Hi everyone, decided/remembered to follow up on this thread. Had no luck finding a spring that the bumper hook is held in with. I see in the pictures it?s just a single wire that loops. Can someone mic. The thickness of the wire? I want to try to fabricate one.
Thanks

A screen door spring from Lowe’s is a great replacement. Trick from Brian. I will post a link to the thread next year. (happy new year)

Played around today with my jack ( no pun ) Made a template with solder a then mocked it with wire. Works great and fits great. Thanks for the original pictures.
