It is probably 6 inches from front to back slope.
But you have to keep in mind that there is no rear axle on the car
now to put jacks under, so I have to put them on frame rails. Plus I need the back up enough to get an axle under there with enough room to work (the back of the car is on the high side of the garage). So in order to get the front high enough to level it I would have to get the thing WAY up, It's already just about as high as it goes. I'll figure something out with Lintels, they are basically solid blocks of concrete (not like worthless cinder blocks) so they should do the trick.
