DD steering shafts question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Dumb question, but I haven't been able to get the answer.
3/4" Double D steering shafts....
Is that 3/4" between the flat machined surfaces?
Or, I'm thinking it's probably the size of the shaft before machining?

It's the o.d. of the shaft, that is 3/4".
Mine shows about 9/16" between the "flats".

Thanks, that's what I was thinking it was.
I was looking for one to fit a S-10 column but it's about 1" on the round portion and 3/4" flat sides. So, that won't work.
Back to the drawing board.

Thanks. That's who I always deal with on suspension or steering parts. I had checked their print catalog before I posted this but only saw 3/4, I'll check their online catalog since it's more detailed.

I don't have the new catalog, mine's a few months old. But, I'm looking for 1" SHAFTS. I didn't see them online.
thanks
