While I agree with the premise of "deciding on your final goal", I have to honestly admit that I figure it out as I go along. I look at "segments" to complete, and categorize them like:
1) Floor - repaired
2) Front end - rebuilt
3) Gas tank - restored
4) Interior - stripped and in process
5) Dashboard - in mid-restoration, have removed and will replace with another restored unit. Have much to still do under the dash
6) Add power brakes - NOW - since the dash is out, I have a power brake booster, and I have the necessary bracket/pedal parts, which have all been restored
7) Windshield - removed, rust on periphery repaired
Headlner - SOON to be replaced as the windshield must be out to do so
9) Rear end - have an 8" to put in, but must restore before swapout. Will also put new rear springs on.
10) Bumpers - removed, all hardware underneath pulled, sandblasted, repainted
11) Inner fender - needs replaced, am lining up folks to do it
12) Motor - not sure yet, will probably build one on the side then install
13) Bodywork - absolutely last.....! Except for the cowl hole, which has been repaired.
To make my now long story short, I have really decided to do EVERYTHING and touch it all as I go. I am doing everything BUT rotisserie restore, which I would have, had I had the time/space/money.
Coming full circle, for me, it's not about the goal as much as the adventure; if I touch it all NOW, I have a wonderful final product and it will be easier next time!!
