I have never heard of them not working, same frame the only thing different is the irs so they should all work. I know I will be getting MM full length this time. On my 00 gt I had kenny Browns and they worked great.
Been AFK for a while but to answer the question about tweak'n the car while on the lift in the pictures above.... just got finished plumb bobing the car, completely in alingment. So I guess min'es a freak or they knew what they were doing while the car was on the lift. Not pictured was several twist style jacks that held the front A arms and rear axles. Maybe that's how it was levelled. I dunno, haven't had any issues so I'm happy.
