I'm with cmayna....I installed patricks kit in my torque tube '53 about a year ago. I basically spent about 2-3 hours each afternoon after work pulling things apart and re-installing, so maybe 6-8 hours total. You must pay attention to detail and follow the instructions that they will send with the kit. The lash adjustment was not difficult. I personally do not think the switch is an enormous improvement - but I feel fairly comfortable now at 60 mph.
