Just curious if anyone knows the differences, if any, in the 61 C-10 and 63 C-10 front suspensions? My 61 has torsion bars, is the 63 coils? The reason I ask is because I would like to convert my classic to an airbag suspension so I can lower it at shows but still make it back in the driveway. I have not been able to find any brackets for the front of a 61, only 63-72. If anyone knows of a solution I would gladly appreciate the help. Thanks
