We're stumped...Can Anyone ID this old steering box ???
#16
Here is a pic of two sector shafts. The top one is from an F4 thru F6 box and the bottom one is from an F1 to F3 box. By looking at your pic I would swear it is from an F1 but the dimensions don't match. Both take the same nut for the pitman arm at 7/8-14 thread.
F1 dimensions:
1 1/8 machined shaft diameter
3 13/16 length of machined area for seal and bushing
roller width 1 1/8
roller diameter 1 5/8
total length is 8 1/4
4 groups of 8 splines
pitman arm hole 1 inch
F4 dimensions:
1 1/4 machined shaft diameter
3 13/16 length of machined area for seal and bushing
roller width 11/16
roller diameter 2 inch
total length is 8 9/16
4 groups of eight splines
pitman arm hole 1 1/8 inch
F1 dimensions:
1 1/8 machined shaft diameter
3 13/16 length of machined area for seal and bushing
roller width 1 1/8
roller diameter 1 5/8
total length is 8 1/4
4 groups of 8 splines
pitman arm hole 1 inch
F4 dimensions:
1 1/4 machined shaft diameter
3 13/16 length of machined area for seal and bushing
roller width 11/16
roller diameter 2 inch
total length is 8 9/16
4 groups of eight splines
pitman arm hole 1 1/8 inch
7RT-3575 .. Sector Shaft: 1948/52 F4/F5/F6.
7RW-3575 .. Sector Shaft: 1948/52 F3/F5 Parcel Delivery & F5/F6 COE
Both 7RT & 7EW use the same sector shaft seal: B6A-3591-A = 1 15/64" I.D. x 1 11/16" O.D. x 3/16" thick.
The former Gemmer steering factory is north of the Edsel Ford Freeway and the former Packard factory in Detroit, both are vandalized and burned out ruins.

Hey Numberdummy thanks for the respone.
It looks like the info you've provide are for the F1 & F4 pics that gearhead1952 provided.
I'm not sure what happened to my original pics but am reposting them now.
Looks like the mount has been re-positioned & re-welded.
Overall length: 8.75"
Shaft: 1.25"
Machined Bush surface: 4.125"
Roller Dia: approx. 1.78"
Thanks,
