Nice work. Easy day for me. Replaced headlamps with Sylvania Silverstar sealed beams.
Changed my TH350 speedo driven gear from 20-tooth to a 24-tooth and verified the speedo with a GPS phone app - right on target. 5% per tooth rule of thumb worked for me as my speedo was reading 20% higher than GPS MPH. Added a spare tire carrier from LMC and bolted in the spare tire. Added a kill switch to the HEI tach lead and tested a few times - works great.
