Achipmunk

Just bought it last year....

I used the bolt on version, but "helped it" with a bit of welding here and there.
Be advised it will lower the back of the truck a bit. Since I have a panel truck
there is more weight on it...so, since I intend on towing a trailer
I am supplementing the new springs and shocks with a basic set of
Air-Lifts" when under load...

I have used other parts and kits from these guys and they make good stuff and know what they are talking about....
