Thanks for the response, Jim.
I see that Original Parts Group carries the mounts for $36.99 each, which is not bad. The picture of the mount, however, looks different than what I have. The pad they show only appears to have 2 bolt holes, rather then the 4 on my mount, and the "ears" that the cross bolt goes through to the frame mount has 2 holes, rather than a single hole. This may be a generic picture, so it may not be an issue. The ad says it is an original duplication. I guess I will order a set from them and see if it is correct.
If, as you say, this is the same mount used in the big car, I would guess that I shouldn't have too much trouble finding a set of cores to send to Steele.
