Jacking points
 

Every time i jack up my 911 3.2 on a two post ramp on the four points under the car it always takes the under seal off,I have four rubber blocks with a slot in them so the pinch welds go in them and not bend them up.

HOW DO YOU JACK CAR UP WITHOUT DAMAGING THE UNDER NEATH.

Anyone

Maybe try a different brand jack pad? Parchment paper?

Is the undercoating adhering to he jack pad or cracking and falling off?

There are 10mm (check size) threaded holes at each corner of the belly pan, just next to the pinch welds. Get yourself four hockey pucks, drill out the centre, including a recess for the bolt head and screw them in. As I recall, on one corner I also had to saw a slit on the puck as the threaded hole is too close to the pinch weld.

Johan is correct in that they are 10mm bolts. I had to bevel the edges that sit against the body at the rear.

Hi
I don't have these 10mm holes on my car

Later 3.2's had jacking points welded to the body but if your car had those you probably wouldn't be asking the question. Guessing you have an early 86 or older.

Your car has the holes, they are covered/filled with plastic plugs. Look carefully in the locations pictured in the other thread and you'll find them.

Do I need to use Montreal Canadian pucks?

You're in Ontario so you'd use Leafs pucks.

Canadiens. Or just call them Habs.

they still do exist in the parts list and you can order These to weld them to the car.

I thaught about it many times to do it...

well, thats a quandry...original montrealer..so big decision

I need to order these parts, as I'm missing one... do you know what the part # is?

It is one of the many little annoying design "flaws" that the earlier Carreras did not have a jack pad anywhere. I have a scissor lift. I use it for a lot of tasks that don't really require a lift, but having the car up higher and not bending over is a lot easier on my back. Even a task like waxing the car is a lot easier when the bottom of the door is at a comfortable height when seated on a roll around chari.

Anyway, I use the slotted pad on the pinch welds up front. It is a slow process to get the lift pad of the scissor jack up close to the seams, but it is fairly easy after many time of doing it. In the rear, there is a flat area under the torsion bar that is perfect for a standard hockey puck to fit.

I have thought of having a lift point tack welded on to make it faster to lift the car.

Could these be the parts shown as #25 on the illustration? 999 103 125 shows as 4 used on the car. 40http://forums.pelicanparts.com/uploa...1551754924.jpg

I agree with Jonny as both my ‘86 nd ‘78 have the threaded holes.

These are just the plugs to fill the bores/thread.

Jonny042 thats a nice looking floor on your car.

we are going t make these alloy pucks soon.
here is a prototype fitted to a friends ST-tribute build
