I can't believe the 38" (38"-38.25) would be a problem for you. It's just a little wider than the frame. Pretty sure this is the answer.

Can you give me the dimension of one axle bracket width, outside to outside? and inside to inside? Thickness of metal?

Also need dimensions of the coilover crossmember. Over all length. Centerline to centerline and diameter of mounting tubes. (the ones that attach to the frame). Then the CL to CL of the Shock mounts.

If there are any modifications to your stock 1954 3/4 T frame or the axle width, whatsoever, now is the time to fess up.
You will have to calculate if the wheels fit.
