Anyone have any experience, good or bad, with the replacement leaf springs that CCoT offers for a FJ40? My brother's 71 is sagging bad to the rear and to the drivers's side and we are trying to come up with an easy way to correct it. Are there any other places to get a good set of springs?

I went and looked a them the other day and they look like very nice springs. I have no first hand knowledge of use, but I have touched and seen them and they look very high quality.
