Yep, you can get just your front drums re-drilled to the 5 on 4.5 pattern. I just did the hubs and drums for my 9 inch front drums. BUT I did use 1/2 screw in studs instead of press in (there really isn't a whole lot of meat left on the hub if you drill for press in studs). I have done the 1/2 press in studs on my old valiant wagon and had about 80k mikes on that setup and it never failed but I wanted a little more meat left on the hub by going to the screw in setup
