I see the Allegro was mentioned above, when they came out there was instructions not to jack up one side and open a door!!!!

I made this as it makes things alot easier
Fits across the front subframe
And the wooden ramps to rasie the car up enough to get the jack underneath since i only have 3" clearence to the sumpguard

I purchased one of these, can be used front and back and fits any car, its just the beam not the jack, fits almost every jack.

Just add..... I got it new off of eBay around £28 delivered last year.

It should never be an issue. The Mini body-shell, in good condition, has a very high torsional rigidity and so long as the shell is not rusty and is all welded together as intended, then the screen cannot break due to jacking one side at the front. However, if the shell is weakened by rust, or has had some structural integrity/torsional rigidity removed by the fitting of a flip-front with, maybe, the rubber sub-frame mounts retained, then the shell could twist, one might guess, and cause screen failure.

[tiger99]

Yes, I also suspect inadequate torsional stiffness due to bad repairs. Remember the one recently, with the sills not welded on the lower edge?

But another possibility, and I seem to recall it happening on very early Minis, maybe to the rear window, was that due to inaccurate bodyshell assembly a rough spot on the inside of the aperture was pressing on the glass, even through the rubber, so check the top edge of the scuttle for any indications that it has high spots.

[Cooperman]

Thinking about the aperture edges, if the scuttle panel ends, or indeed the complete scuttle panel and/or inner lower screen rail, have been changed and the aperture edge is either incorrect size, or not correctly profiled at the corners it could perhaps cause screen breakage if the shell also flexes slightly when being jacked. I've been jacking Minis under one side of the front sub-frame for over 50 years and have never had a screen break.

[lrostoke]

you would imagine that if the aperture is wrong theres a strong risk of cutting into the seal, which could leak

[Cooperman]

If the aperture is slightly too small anywhere it can be very difficult to get the screen into the rubber and then get the locking strip in correctly. If a screen has broken when the car was jacked up on one corner, personally I suspect that the structure of the body is not as it should be and the body-shell is actually flexing diagonally. Fitting a flip-front could cause this, especially if the bracing does not take the torsional loads correctly into the rest of the shell.
