Your C10 power steering box -- Lock to lock to turns?

On your power steering box, how many turns does it have lock-to-lock when installed on your C10 truck? My 69 C10 box itself has 4-1/4 turns when sitting on the bench. However, when connected to the steering linkage it has only 3-1/2 turns because my 85 spindles' "stops" hit the lower A-arms. I'm just curious if yours has the full 4-1/4 with stock spindles.

My truck has been this way for around 25 years since I installed the 85 spindles, but I just now realized it when installing an AGR Steerco box.

Yes, the original boxes are around 4-1/4 turns of the original size steering wheel. Sounds like your spindles are stopping your full range of steering.
