I wish I had the time, and space, for that many projects!
You don't have to actually mount them to measure. If you can literally lay a straight-edge across the bottom of the WFO and measure up to the carb mount, then up to the shaker lip and give me those 2 numbers, I would be all good.
Don't want to cause you too much work, and those 2 measurements are all that I actually need.
