C30 Rear shock Question!!

[GloryHound]

Where rear shocks on the C30 duallies an option or did they come stock? The leaf springs on these trucks are so heavy I don't think a shock is going to make a lot of difference and my truck does not have rear shocks or upper shock mounts. The mounts are on the axle but not the frame. Nothing on the glove box option sheet says anything about rear shocks, but I have seen it mentioned on C20 and K20 sheets but even the ones that don't mention it seem to have rear shocks. If this is only an option where would I find that info to show to the inspection mechanic so he does not fail me becouse I have no rear shocks which are now mandatory? If this is standard equipment does anyone out there have a pair of upper shock mounts for a C-30 that they would be willing to sell me?

Thanks for any help!!
