Yes, I would. Thanks for checking.

Oh, you want to know the size? Why didn't you say so? 1.087"

Absolutely! Caffè Verona followed by French.

I had the perfect pair of trucks with which to answer the question. Big Blue has the cable through the firewall and Dad's truck doesn't.

Excellent, thanks Gary.

I just recently ordered some 1" plugs for the holes in the bottoms of my cab corners, and I was thinking I should order one for my speedo cable since I will be replacing it. Mine has some goo or seam sealer spread on it so I didn't want to rip it out just to check it.
