What width tube axle in 62 Falcon

Planning on hanging my tube axle in my 1962 Falcon and the one I have is about 49 in inches center to center on king pins. I am thinking I want about 44 or 45. What are you running? I am running Shelby 15x4.5 Wheels. Also can any one tel me if this looks like Econoline spindles and drums?

 

The Falcon was 55" wheel flange to wheel flange.

 

I put a Speedway kit in mine. 48" center of king pin to center of king pin was perfect .

 

^^^ thats what I bought for the 62 comet

 

Econoline axles are 52" kingpin to kingpin. If you have one that's 49" I think it will be perfect myself. Some people run narrower, but they look weird when you get the front up and go narrower. I'm running a stock width Econoline axle in my '63 Falcon with 15x4.5" ET Classic spokes, and 185-15 tires. It's right at the edge of the wheelwell, and the sidewall of the tires actually hangs out past the fender. Probably should have cut the axle 2"-3" prior to putting it in.
This was a mockup picture, with front fender just hanging there to judge the width then:

Those don't look like Econoline backing plates to me. Bolt pattern on the wheel cylinders looks too narrow. Raised area on the backing plate looks different also.
