I found a 66 ford big block mount at the local parts store that looked right but did not work. I got several from several different local stores plus a set from Motorsports International. They all were close but did not work. I finally found a pair of original old stock units that worked. From what I understand there were some differences in the original mounts. I have included a picture of the mounts that didn't work. I will also send a picture of the mount that worked. I had changed the mounts earlier and bought a set directly from Ford so I didn't expect any problem and so I had tossed the old units before I tried the new ones.

Have fun, Ray
