65 Barracuda Disc Brake Conversion Help Needed

Do they make a dropped spindle for 65 'stock' application? I got the 'ol torsion bars turned down which is not ideal...but is free and hasn't seemed to change anything drive-wise. Im using OEM 67 stuff so it was 'almost' a bolt on as I believe I used the 10" Drum LCA (brand new) and just drilled out the 1/2 bolt holes to 9/16 (very slowly and LOTS of cutting oil as only the tip of the drill flutes contact the metal). that was the only difference between the disk and drum LCA's for that year.
