273 motor mounts

Early A's are thicker. You can install the later, thinner "biscuit" mounts by drilling a shallow locating hole and cocking the mount. It did that to gain hood clearance, but the later Federal p.s. pump I used hit the K-frame. "Should work" w/ the original TRW pump, but also consider the driveshaft angle change. BTW, the same brackets & mounts work w/ a 318 or even 5.2L Magnum engine (I think).
