I have one on my 79 camper. I got the front and rear end kits. It handles well compared to previous which used to wallow all over the road.
I do worry about whether there is enough strength in the set up though as all of the front end is now supported on the shock absorber bolts. If one of them went, the body on that side would drop instantly and hit the tyre. I'd like to think I could get new aircraft quality high tensile bolts for this, but the lower one is actually a rod inserted into the upper trailing arm, and I'm unsure how to get this out.
