Some penetrant eased the stiction and I was able to jack it up to the top. The snap ring was a bitch to get off but once I got it, everything cam apart as it should. Thanks for the help.

My snap ring is badly eaten away by rust. Let me know if you have a source for a proper-sized replacement.

The tube diameter at the top is 20 mm and the snap ring is 2 mm thick.
One of these should work

Thanks for the info, Tom. The remnants of my ring appear to have a round profile, not square. But that one should work OK for my driver level car.

If the ring is structurally unsound I don't have an answer for you. If it's just ugly looking you could take it to your favorite chromer and ask for nickel plating. That's what i did (although I've only restored the earlier style jacks carried over from 356s). You risk making it a little over-restored that way.

Did Porsche use the exact same VW jack in the LWB Porsches, or where there slight changes over the years? Is there a part number stamped on the jack to identify it (e.g. ABxxx)? Over the last few days, there have been 2 threads that had pictures of 70-73 original 911 jacks, but I noticed they had slight differences:
PET shows three part numbers for jacks from 1965 (actually 1955) through 1973:
- 644.722.010.00 Jack -68 (That's the one on the right in both your photos, carried over along with its part number from the 356. Those photos are the final variation dating from about 1963)
- 914.721.010.10 Jack 69 - 71
- 914.721.011.10 Jack 72- (This happens to be the only jack part number in the 914 parts catalog)
The jacks on the left in your photos look more or less like I remember 914 jacks--I'm no expert there. One could well be 914.721.010.10 and the other 914.721.011.10 but don't ask me which is which.

This is the one photographed in the model year 72 drivers hand book published VIII/71. It may not be conclusive as Porsche obviously recycled images from previous year's manuals and sometimes staged shots with accessories and tools other than production final version.
I don't know jacks from before screwtype but sharing it for what it's worth to be a comparitor to jacks posted because I had the 72 manual to hand:
Attachment 514138
Attachment 514139
Attachment 514140
This is the similar illustration from the driver's manual one year prior published VIII/70 for the 71 edition
Attachment 514154
Attachment 514155
Clearly some differences
Also somewhere I have a surplus jack of the older type that preceded the screw one that came with my model year 73 car.
By the following 73 model year's driver manual they had updated the equivalent image to show the screw jack image ( the distinctive up down black writing on yellow (not green) dot) screw type that I recently posted a picture of elsewhere.
Do these versions printed in Porsche's own publications with date and model year tally to the part number evolution in Jim's post above (Porsche manual photo reuse and online PET supercession notwithstanding)
