The Z.F. steering gearboxes were assembled with four large bolts. One of the bolts was 3/8″ longer than the others and had a hole drilled through the exposed end. In that hole was a lead seal to indicate that the gearbox was original and had not been apart before it was used in the car. Reproduction Lead Z.F. Steering Gearbox Seal

For the long distance races or others when there would be a chance for rain Ferrari would use rubber boots to cover the distributors to keep the rain water out of the electrics. There are good photos of the T.R.s using these boots at Le Mans. Small Distributor Boots for the Front – Mounted Distributors
The very early Ferraris had the exhaust system mounted solidly to the chassis. They later changed to a type of hanger with metal ends and flexible center section made of belting or truck tire sidewalls. The early ones were what are called the “Center-pull” design. In this configuration the four steel components are all the same design. These end pieces are all bent so that the force goes through the center of the assembly. This design was originally painted black until the mid 1950s when a change was made toa cadmium finish. Later, about 1962 during the run of the 250 GTEs the hanger design was changed to the more common “Side-Pull” arrangement. Black-Painted Center-Pull Exhaust Hangers…(24 to 28 per car)
