MGA cockpit rails, dealing with aftermarket parts

We start to tackle the cockpit rails on the 1960 MGA before finishing the carpeting ( the rails should really be done first anyway) we discuss some of the challenges with installing these as the bodies on these cars were largely hand made making for slight differences from car to car. Also, since we are working with mostly aftermarket pieces instead of originals they offer additional challenges as the only real consistency in the aftermarket ones is that they haven’t been right for years. It takes a bit of time and effort to make them fit the car and look nice once covered
