Tonite I started disassembling my '70 140 dash to replace the dash decal. I didn't know the column had to come out to remove that large grommet. I've been going thru the service manual. It gives a detailed description of one method, then gives another method with really basic instructions. There must be a a catch. which is the preferred method? I kind of like the second method (out from under the tractor) because I don't to have to pull that one support and have screw heads showing on my new dash) but there doesn't seem to be much room down there. I wish I'd thought about this before I put the engine back in, but that ship sailed several months ago.
