Yes. The 1200 pickups and travelalls changed from 6 on 7.25 to the ford/dodge 8 lug pattern in the 69 model year, when the body style changed from classic C (round) to classic D (square). The frames remained the same through the 73 year. The usual disclaimer applies as to what constitutes a 69 pickup or travelall. I have a pair of 66's sold as 67 and a 68 sold as 69, (which in my mind is a 68 so that IH type people will know what kind of vehicle it is) and have swapped 73 1210 axles onto a 66 1200A travelall with absolutely no problems. Perfect fit. I am about to do the same thing to a 60 B120 travelall, and I believe it will also be a perfect fit.The 3/4 tons switched between '66 and '67.Hmmm...I have both a 1200B('67 2WD) and a 1200C('68 2WD) that are 6 lug. JimHmmm, indeed !! :-) Greg
