Hot Rods What hub cap can I use...

This is a 39 Lincoln Zepher axle (may be the same as Ford) in a 29 ford sedan..what hubcap can I use...the axle extends out pretty far.....the wheels are ford originals..5x5 1/2.. 5.5 inches wide..I wanted to run an early 50's hubcap...
TIA..Steve

 

I'd start with early F 100 caps if the nubbies have the 9-1/2 inch circle for the early caps. Later caps had a 10-1/2 inch nubbie circle.

 

Kinda looks like a late 60's - mid 70's wheel. Ford pretty much had a flat (kind of deep) dog dish for those.

 

I'm running 49 merc wheels in the rear and can run the 50 merc caps on my stock banjo axle.

 

'51 ford

 

Thanks everyone, haven't decided on hub caps yet..I'll post a pic when I do....I did pick up some ribbed beauty rings....
