Hot Rods F1 gemmer steering box info

So I’m looking for a 48-52 f1 steering box I have a few 53 and up. Does anyone know if the sector shaft from a 48-52 fit in a later box? I ask as these earlier boxes are becoming hard to find and I see they sell these sector shaft but no one can give me dimensions on the early shaft. Any info would be greatly appreciated

 

Sorry, it won't fit. The F100 sector shaft is larger in diameter than the F1.

Ive got a few in stock, I have a couple F1 boxes and a F3, the F3 in a Model A is like power steering, it uses a larger pitman than a F1. I normally sell em for 300 when I sell one.

 

I’ll get ahold of him! Thanks
