My original: The offset of the hole is 46 mm, the height is 66 mm

The westar EM-2110: offset 8 mm, height 75 mm

Can you put a tape measure to the two pictured motor mounts and give us a ‘height’ measurement?

Thankyou for the excerpt, Ted. Now I've browsed a lot of models and their motor mounts. But no luck to find something like mine. Also thanks for the link to “Hemmings motor club”; That might be an option.

This is about 20 years ago, before I inherited the project from my father.

This is a recent picture. Its a slow moving process...

When looking at the Ford, Mercury, and truck parts catalogs, be sure to look at the other engine families and not just the Y.  The FE and M-E-L engines shared the same block motor mount bolt patterns as the Y.  With this in mind, also look at the FE and the M-E-L motor mounts.  In looking at the 55/56 Mercury catalog, the Y-Block motor mounts (basic part number 6038) for 1954-1955 are different than what’s listed for the Ford and Thunderbird vehicles.  Here’s the excerpt from the 1959 Ford catalog.

Any pics of the rest of the Allard?  Sounds cool.  

If unable to ID take-offs, maybe here -

I'm restoring an Allard with a 292 y-block. I got new motor mounts, but they do not fit.This shows the problem:

The original mounts are lower and the holes are displaced compared to the new ones (Westar 2110 - Thunderbird 1955) The chassis of the Allard was modified in 1955, to "upgrade" from a 1950 flathead engine.I've browsed motor mounts for a lot of car models without luck. Any help identifying these mounts would be appreciated.
This post,  "55 Ford fairlane engine mount", seems to address the same topic, but without conclution.
Here is a picture of the project with the original mount
