Thanks Dan! Appreciate the welcome back! Also updated the link so it should start working again. Moved the recent madness of me measuring and looking high and low for any and all numbers on that axle. Did confirm tonight that the U Joint will indeed fit the 66 side and will try to get the 52 side punched out tomorrow to check fitment there. Gonna save some cash up for the 4 link while I put everything back to mostly original to see how it sits and maybe drives later. Already have the spring perches ready to weld on once I get the correct angle on the driveline done.
