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

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?

thanks for all the feedback
when putting jackstands under do you jack the car up 12" and put a stand in place and then go the other side or do you go back and forth inch at a time or----any technique to minimize potential damage?
