One simple word of advice.
PLANNING
If you work for any business, you will know that business planning is paramount, you should treat your restoration in the same manner.
Step one, decide what exactly you want to achieve, concourse restoration, bullet proof every day ride, weekend tourer, acceptable for vintage roadworthy example of the marque, hybrid Z.
2 READ everything you can find once you have decided on what your end goal is.
3 Examine clinically every part of and every part on the car and decide what can be used without any rework, what needs outright replacement, and what can be salvaged and repaired.
4 Spread sheet all of the above and go window shopping for what you need, price it all up.
5 Decide what you can and cannot do and divide it into 2 columns, what you cant achieve you need priced by someone who can
6 Don't lie to youself.
7 Run the adding machine then add a 5% contingency.
Result: reality bites.
Cheers
