I bought the $17 NAPA version of those early Ford mounts and they don’t work with the early CR frame brackets.
Royal and Chicagowil have the new style mounts where the motor mount bolt goes down into the frame bracket verses the horizontal bolt like the Mustang II pair I posted a picture of uses.
Post a pix of the newer frame brackets with a steel cut sheet and we can make them and use the mount for the later Mustangs that they still sell.
I’m not convinced Royal has the newer style frame brackets. Post some pix and dimensions if you do.
These are the original version horizontal bolt CRI brackets that use Mustang II motor mounts.
