I run a narrow F103 as well, but kept it to a minimum cost. Parts used were:
Tamiya 51380 F104 D Parts - just for the servo mounts.
Tamiya 51381 F104 F Parts - front suspension arms.
Tamiya 54160 F104 Titanium coated kingpin.
Tamiya 53599 Fluorine Coated 5mm Aluminum Ball Nut - for the inner upper arm mounting.
Tamiya 54161 F104 Low Friction Sus. Ball Set - for the outer pivot balls. Plastic versions of these are included with the F104 F parts but these are smoother.
A pair of 35mm turnbuckles.
Everything else used was taken from the F103 front end, steering arms, screws, springs, e-clips, steering ball joints, etc.
If you have an adjustable ride height F103 rear pod then you don't need to change it to F104 parts, the F103 pod on its lowest setting should be fine. In my case I had the older fixed height rear pod so went for the 3Racing F104-09/LB Motor Mount and 3Racing F104-10/LB Rear Wing Mount parts to make an all alloy rear pod and the Tamiya 3450157 8x16mm spacer to fill the gap on the axle. The F103 diff is also used in the F104 so you don't need any parts to change it .
