Okay... they are very similar except the 479237C1 uses a smaller hole yet still uses a 5/8" bolt. All I would need are the big washers, so... if I manufacture my crossmember in such a way that I have 1/2 inch of material with 1 3/4" holes, i can use them inverted under my stock front bracket. Excellent! I have stock Ford Louisville rear mounts which will also be very nice to use. Thanks everybody for helping out the new guy. Here is a video of my engine after giving it a complete tuneup, but before the fresh coat of Alpine Green.
