it's not a lack of interest on your grandpa's part i was thinking about
it's the fact it's your car and i think as it's your first real attempt at doing this type of job on a car and it's a bit of an undertaking to go to a resto job are you going to go right to the bare shell?
as i say many would be put off by the sheer scale that type of job i have done them as body shell jobs and on a new car it would take about 30 hours or more to transfer all the bits (a lot more on a rr / lr) dont forget the frozen bolts it's all time
and good luck to you if your stuck just give me a shout
painting is straight forward with the right gear (wait for flack from painters )
