In FUC-03 the insulator is listed as;
09B-6038.
Macs sell an insulator on its own. 78-6038-S
They sell two mount assemblies:
1. B-6038-S. This one has the big steel cup washer that has the 1 1/8" hole, that is correct for the carriers. (washer part number 78-6048-A)
2.B-6038-C this one is the correct part number (for a carrier) but cup washer is wrong (small hole)
I don't know if the insulators are the same
Lastly the jeep has a similar looking mount supporting the transfer case. This one is part number 74-6038 It is possibly a softer mount.

I guess the whole point of this post is that you have to be a bit careful to try and get the right parts. Many off the various mounts may have been produced with not too much care (or need to care) if a mount they made was an 1/8" too high or low at assembled height.
At the end of the day, an extra washer between the water pump and the insulator will likely fix any discrepancy.
The MB/GPW mounts are very similar, and these are still being made today for Indian made Jeeps. While not technically a "repop" part (they are a factory Jeep part), they are being sold by a few sellers in the States as replacement for WW2 Jeep (OK) and Early Fords (Probably not OK). Example. The reason that the Jeep mounts are softer is that they are hollowed out under the large cone. I'd be wary of their installed height under the weight of an engine, and their compression rate.

Series 1 Land Rovers also used the same mount for the Transfer Case, and these are also being sold new through various UK LR specialists. Like the Jeep mounts, these only support the weight of the transfer and are also significantly hollowed out.
