Unfortunately, I found very few classics in my club, and even fewer people who actually work on their cars. I find that frustrating, because I like working on things, and talking to like minded people. If you don't have some natural mechanical ability, it will be very difficult. I have one son that doesn't know one end of a screwdriver from the other, but his younger brother will attempt anything. I figure I could do anything, but there are some things I just don't want to do. For instance, I think hog ring pliers would make my arthritis act-up, so unless I can fashion a pair with long handles, I'm not going to attempt upholstery. You will learn techniques as you go along, just by trial and error. You may need to do it over one or more times, but so what? You'll probably do it better than most shops- and believe me that is very true. Only one in four professionals are competent at what they do.
With help and guidance from a group of guys like we have here, you will get it done. These are are fairly simple machines, and its not rocket science. Much of it is unbolting one part and bolting on another. I had never welded until recently, so I bought a welder and through the use of videos, I practiced (and practiced) (and practiced), and finally built a ramp to get one of my cars in the garage (its one of those plastic cars that we don't like to mention on this forum). The car is too low and the driveway too steep, but now I can drive it right in.
If you think you can't do something, you're right. If you adopt an attitude that anything you mess-up can be fixed, it makes a world of difference. Just remember that nothing that anyone does is perfect. I tend to be a perfectionist and constantly have to remind myself when something is good enough.
