69-72 Passenger Seat Bracket Question,...

[lolife99]

Does anyone have the dimensions for the steel non-adjustable seat brackets that are used on the passenger side bucket seat?

I have access to steel and a sheetmetal brake,... so I'd like to try and fab up a set.
I don't have any brackets for a pattern, so I thought I'd see if any of the members have those dimensions.
Any help would be appreciated.

I borrowed this picture from Classic Bowties thread.
The brackets I want to make are on the left.
