    Many used items in our pictures have been cleaned and/or bead blasted prior to being photographed to show condition and detail. 

    The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned. 

    We do not retake pictures each time a used item sells. Pictures are a good indicator of what you will receive, but not all used parts age the same. On high dollar parts, email us and we can send a few pictures of the actual part available.

    "Core" Items:
     If we use the word "Core" in the title of the product, the item has been deemed rebuildable, but has not been rebuilt.  The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned.

    Used flexplate reinforcing ring, Ford called it a fly wheel reinforcing plate. Fits all Ford small block engines including 260, 289, 302, 351W and 351C. Strengthens the area where the automatic transmission flex plate mounts to the crankshaft. This is not just a ring with 6 holes in it, it is indexed specifically for the flex plate and only goes on one specific way. It has to be indexed because of the weight on the flex plate. Just under 4 inches in diameter. Special bolts not included, but available.

    Fits: 260, 289, 302, 351W, 351C all with C4 or FMX transmissions.
