4. Installing the Door Sills
Next we will focus on the door sills. On my ’73, it has the sills that include the rubber channels (yeah, most do). These channels have a lip that needs to GO OVER the channel. DO NOT ATTEMPT to bend the rubber around the channel, that would be ludicrous. Go ahead and fit the driver’s side piece in the channel and see how it lays into the pan. I made 1/2 inch slits on each end of the seat rail to ensure proper fitting. No other cuts were required.
