tried posting this in the edge forum I'll try here, anyone ever swap 2005 900 rmk 159 skid to edge rmk 144 chassis 2003, seriously thinking about doing this parting out 900,mind as well use good track, Anyone?
I can't remember if the Suspension mounting points are the same with the Edge / Dragon. ( your 900 is the same as a Dragon / IQ) Measure from arm to arm mounting on the tunnels . Width is ok.
Look at the rails and see if the front arm mounts in the same distance back.
