Hmmm. I'm doing my springs right now and I think you were lucky on that jimbo I got one side in perfect and can see the end of the spring in the hole on the top pocket of the frame - but it wasn't easy. Took many attempts. If the spring is not in there perfectly, simply whacking it with a board will not get it to sit in the pocket correctly. He may have to try and use a spring compressor and twist it into place, or what I had to do which was remove the spring, compress it, hold it up there and get the end of the spring to lign up with the hole in the pocket, then with the other hand jack up the lower control arm until the weight of the car is on the spring, then re-check if the spring is still seated properly (it tends to twist when you start to compress it) then re-connect the lower ball joint and remove the spring compressor. Others seem to have success with the all thread method, but I don't see how you could get an uncompressed spring to sit on the lower control arm without messing up the top alignment. Just my 2 cents. Good luck.
