I bought it a very long time ago from a place that is no longer in business.

There are no markings showing the manufacturer name etc

Under the white cover of mine is an opening the size of the cover with a screen to catch the drain plug.

I use a $1 flexible cutting board to deflect the stream into a $2 bucket
Works perfectly. Just spread a towel underneath to catch any spill.

If you jack the car using the Pelican insert to the jacking port, don't max out the jack & place a jack stand under the torsion bar cover at the rear. At a big enough angle the torsion bar cover, with the weight of the car, can "squirt' the jack stand out of place allowing the car to fall and create much mayhem as the car will fall down on the displaced jack stand. There is a photo on this board somewhere where the jack stand gouges a hole in the body panel. Just beware.

I have done this numerous times with no bad outcomes.

I have noticed that at times as I SLOWLY lower the car onto the jack stands, they become angled. I merely raise the car back up and adjust the stand position appropriately and lower SLOWLY again. I repeat this until I have the car on the stand and the stand is firmly placed squarely on the floor.

Can you find the picture?

If you do lift the car use something to distribute the load over a wide area, you can use wood blocks, hockey pucks etc

I use these

try not to lift on the pinch welds but if you do, use a slotted block

be extra careful of the oil line

I use 2 low profile pans a small one for the cc and a larger for the tank, I find that straddling a swale in front of the house is convenient as it provides a little more room under the cc.

A lift makes it really easy, but it's certainly not necessary

13mm socket and a 6" extension for the tank plug

put a rag under the filter when you loosen it. I cut up an old plastic milk container does the same thing.

This! I made these last year, use them for all my cars when all I need to do oil, etc. Plus, since all of my cars are lowered, it can be a pain getting the jack under the damn cars. Roll up on these, presto, then use jack to your heart's consent. I also use what Bill posted which is a pinch weld adapter, that works awesome for the two other cars I have, in a pinch. Hardy, har, har. :)

My oil pan of choice for the 911 is a plastic concrete mixing tub I found at Home Depot. Low, cheap and very heavy polyethylene. Catches lots of oil in a hurry.

I jack '73911 with a floor jack with a 2x4 on it in the center of the transmission. Jack stand at the jack points for safety and drain.

I use the factory jackpad with the rear wheels on cribs. If you want a product vs. making out of wood, our host sells them:

Someone mentioned the thread about the car slipping off torsion bar covers, I believe this thread (post 6) has the pictures you were looking for:

Great thread...thanks!

... believe Fumoto now sells this with a safety. Couple of different configs available.

.

I've never needed ramps.

Rear. Jack using side adapter then jack stand on the torsion bar cover.
Front. Jack using jack point wheel well then jack stand on a-arm

Fumoto's are nice but you can just put a shop vac on the fill port to slow the output down. Personally I just get the oil to about 100F and use the plug to slow it.
