A500 in a 1970 A Body

I think this is about the 50th time I said this, but the 518 fit in my 75 Sport with zero floorboard mods. The crossmember hoop connecting the torsion boxes together had to be cut down and rewelded, but otherwise it fit fine.

Just to be safe, 2x2 inch box subframes were welded in, and a beefy trans mount was fabricated to strengthen the torsion boxes also. The car has a rock solid feel to it.
