The SS SYE is 3-1/8" shorter then their HD SYE and some sites say 2.25" shorter then others. The JB SYE is 4.5" shorter then OEM. So in a round about way, it's 7.625" shorter then OEM.
It say's it's s smig shorter then an Atlas II with the gear driven VSS. An Atlas is 13.8".
With the SS SYE, I'd need to lengthen the front driveshaft and stretch the T-case shifter. Then something to recalibrate the speedo signal.
VS.
Moving the engine forward, bending and welding to the floor shifter. So a SYE and I'd actually gain rear driveshaft length. Do a SS SYE and The rear shaft would be 21".
Seen those picts, would like to see engine and T-case skid mods. Interior floor and shifter would be ncie too.
