Couldn’t get that tool to work on a h30 either....had to adjust
Got this black later 60's shroud soaking to strip the paint and crud off as I type, will be cutting the half moon out of the top for the plug and welding up one hole for the tag and relocating the hole as the old Lauson style red tags are shorter than the later versions. I am on the hunt for the intake/linkage cover that these used and were bolted to the intake.
