What kind of bed do I have?

[Luke Nelson <lnelson@domain.elided>]

I have a 70 1200 pickup, I think that the bed is a stepside.  But I
thought that stepside beds has the wheel wells on the outside (meaning
that the box is completely rectangler)  But mine has these huge fenders on
the rear and between the cab and the fender is a step.  

I think that i should grab my friends digital camera and post a pict :)
but if you could help me on what kind of bed I have that would be great.

Thanks,
Luke
