Is there a simple way to get a 914 jacked up enough to change oil Options

[dlindzey]

I can't even find a shop willing to change my oil so I am going to have to crawl around on the floor for a while. I have all the parts and a creeper but get confused on where you can put a floor jack and where you should put a jack stand as seems like same point is best for both the jack and the stands.
I have located the 4 donuts at the corners of the cab/chasis juncture, they seem ok. I am tempted to just get two floor jacks and jack up the rear at the donuts and call it a day. Is it dangerous to use jacks for support rather than putting a jack stand under there somewhere?
Ramps won't work as exhaust tip hits the ramp.
How do most of you solve this issue?

Low profile (Daytona harbor freight) jack Placed in the center under the engine support bar Using a 2X4 the length of engine mount bar
I jack up the car High Enough to place Quality jack stands under the Donuts
Lower the car onto the Donuts Keep the jack still under the car under the support and pivot the jack a little so I can still roll under with the creeper
After chasing a leak you get pretty proficient jacking the car up not F1 pit stop fast
but fast
