as i rember, the front spindles are basically the same after hydraulic brakes were introduced to the Ford line, axle widths and drops are different over the years but the spindles work. I used to use 46-48 items because at the time they were almost give aways.

The 39 deluxe and all 40 car front ends are the same. $1thru 48 look the same but are slightly wider, I think. 35 thru 38 are all the same dimensions, but have mechanical brake backing plates and other special items to mount levers etc. They can be upgraded to hydraulic brakes by using backing plates off the 39 standard, but you have to get inventive to adapt tube shocks.

Ford "Straight" axle front end

Under the assumption you are building a 27 track car you will have several things to consider from what follows.
You can use the front suspension from 28-34 which has the front spring mounted above the axle on perchs. You can split the wishbones and have a very traditional front end. Use Ford spindles a set of 37-41 (round flange) or 42-48 (square flange) and you'll be able to have the choice of early style 40-48 barkes or many disc adaption kits.
You can use the front suspension from 35-41 which has the front spring mounted in front of the axle. You can cut off the spring hangers in front of the axle and , after splitting the wishbone, weld spring hangers to the "bones" and move the spring behind the axle. Again, a traditional approach even if you leave the spring in front of the axle. And, of course, any 38\7-41 front end will have usable spindles and the 39-41 hydraulic backing plates and hubs. (NOTE: 39 Hubs are useless unless you want to use original 4.5-16 wheels as they have an odd 5 on 10.25" circle bolt pattern)
You can use the front suspension from 42-48 which is pretty much the same as the 37-41 except the wishbones are shaped differently in late 47 and 48. The brakes and spindles are OK as is once rebuilt properly.
NOTE: you'll be removing many of the spring leaves if you are using original springs on these front ends. You always keep the main leaf(of course), leaf 2, remove every other leaf (that is For a nice working suspension you'll usually end up with between 5 and 8 leaves.
