K frame swap question

I have the front disc brakes off the 73 swinger. The only reason I want biscuit mounts is b/c I already purchased the motor mounts from TTI to fit the 5.7L Hemi and they are only for biscuit style mounts. So I figured the easiest thing would be to either get the enitire front off the 67 barracuda and change everything or pick up a cheap 1973 and up v8 K frame cut the spools off and weld biscuit mounts on. By doing this I don't have to change the pittman arm location or change the idler arm nor center link. Does that sound right?
