Made additional custom ramps out of pcs of 2 x 10's that lock into holes of purchased steel ramps creating an acceptable angle to drive the car on ( or back on) . Then if needed , jack up rear under the pumpkin & use 2 stationary jacks under rear pads for safety . The car is safely elevated .

I find the recent 3 ton Harbor Freight 3 1/8 " minimum height floor jack very handy for $100 . It has dual lift cyls & goes up fast .
