OK I thought I had this thing licked but have come up with a problem. I did the Tardell suggested installation of an F1 steering box in an A frame by cutting off the A snout and welding it to the F1 steering box. All that went quite well. Now that it is installed I am having a problem with clocking the pitman arm. On the bench I get a full 2 to 2 and a quarter turns lock to lock. Everything is tight and there is minimal play. Installed on the car I can only turn left and when I come back to straight it is locked out. This is with me having the sector gears notches at 12 oclock so the pitman arm hangs straight down. I noticed on the bench that to go lock to lock in both directions the sector notches were at 11 oclock and 2 oclock. So I thought maybe I had the Model A snout not clocked properly to the F1 box so I took everything apart and cut them apart again. I bolted the snout to the frame and inserted the sector gear in the box and then through the snout with the gear in what I think is the proper position which is straight down or 6 oclock like is shown in Tardell's book about doing this conversion. That still hasn't solved my problem. Anyone have any suggestions??? You can see the chalk marks are not at noon and my drag link arm is on a near 45. It should be straight down no???
