Hi v8tvfarmgirl, I saw your own truck feature a while back, nice job!

AFAIK the internal width of both the 46 short and long beds were 48 1/2".
There's more technical data available here.

I'm not sure about the Jim Carter parts,so I can't comment about quality/fit etc.

I hope this helps to some degree.
Jock.
