Rear Motor Mount(Shim) ?

[History]

Both sides had this welded to the top, doesn’t look to be a crack repair/bridge. Can anyone tell me why this has been done? Can’t get my head around it unless it’s to mask a sagging frame for better drive train alignment. Any other thoughts or ideas??

If the bolt holes are egged out to match,I would say to make up for a saggy frame.If they are not egged out,I would say it was done to make up for a badly worn flywheel housing.

Bolt holes are not egged. The piece that was welded is ford marked which is probably a coincidence, probably cut from an existing part? If you enlarge the 2nd photo you can see this.

if the frame sagging the throttle can hit the firewall. something is not correct.

 

[History]

Should the top of the frame be level the entire distance? With the engine out I believe I can use a laser level and see what kind of shape it’s in, I believe?

 

[Flathead]

Frame should be level.

I suspect the mounts were shortened to make it easy to install an engine.

I see your reasoning but the other side looks normal and same size except for the added piece. I think it probably for a sagging frame now. For others reference,,, you can’t use a laser level to check frame with just the engine and transmission out, still too much in the way.
