yeah, stay away from Magnumn force. Not a big fan based on what's been posted about failures. PST is good and even gives a FABO discount to members as well.
I `ve got a complete magnum force tubular front end and haven't had a bit of trouble out of it. I did build a pair of strut rods , much like the originals for it.
I did contact them about my coil over front springs, they were very helpful on the phone, to me ! ??????????
