Front Cab Mount Help

[Grandpas 72]

I am in the process of removing the drivers side cab mount so it can be replaced. While looking at the bottom of the cab, there appears to be a plate sandwiched between the actual cab mount and the floor of the pickup. This plate starts at about 3/4 of the way inboard from the door pillar, and runs under floor support that runs front to back. It is also wider than the cab mount by 6" or so. While drilling out the spot welds I got a little excited and drilled out the spot welds that attach this plate to the floor. My first question is:
- How bad have I messed up by doing this and
- Does the cab mount attach to anything else besides the floor and this plate?
Thanks for the help,

This is what a front cab mount should look like

Does anyone else have any idea as to what this plate is that I previously mentioned? I think it's just a doubler to add strength but I am not sure.

I don't recall any such plate on my '67. The bottom of the cab makes contact with the washer or shim that sits on top of the bushing that sits on top of the rigid frame perch.

That area of the cab is reinforced a bit, but not with an externally welded on plate methinks.

Post up a picture.
