Danbuc, you are lucky indeed. Cinder blocks should NEVER be used as they will frequently crumble under the weight alone, much less the shock of the car coming down on them.
Funny you should mention this Submariner. I had the same problem and just fixed it. I took a 2X12 (2X8 would work) and cut two lengths. One 4' and one 3'. Put a 60 degree bevel on one end of each and screwed one on top of the other with the square cut ends lined up. What you end up with is a step up from the ground to one 2X12 and 12" later another step up to the second 2X12. With the ramps at the end of this additional ramp you now have the clearance you need to clear the front fascia. I now am able to use my ramps again for the first time in many years.Onalaska...........Ramps are the best way to go, BUT, my STS and probably others, is/are too low in front to allow their use......PITA (BTW...dial-up sux)
