ok - first things first - you need to log everything you take off and label up wires if you want to mod or use them later on as well. Bag up all little bits together and label them and log then in a book - so you can put back together again later....
prep work is the time consuming part on a strip down, but will save you loads of time later....
I always do a strip down a car this way.
1. Engine area first
Then put car on axle stands - so can work on underneath.... - you might want to make a jig to sit the car on to move it about when all the underneath is taken off...
2. then underneath - exhaust, brake pipes, fuel tank, fuel pump, rear beam - to refurb... then suspension, brakes off - gear linkage underneath car.
3. Then from front of the car going backwards - take everything off the car outside.
4. Leave the interior last
5. take off glass
If you are going down the route of new suspension for lowering etc, then take them off last so you can mod arch's etc then play around with suspension until you get it how you want and then once all done - put old suspension back on for prepping the rest of the car bodywork and get bodywork sprayed if needed.
Then rebuild starts.....
Refurb underneath parts, install new Suspension, brakes, brake lines, pump, tank, then engine area - get that all working, then work on the interior and then put all the outside parts on...
That is very short list, but it all depends on what you are looking at doing...
KEY is prep work - make a plan of what you want to do first and keep to it....!!!! (if you can) and make a plan for taking parts off and how you put it back on as a few months along your forget...
Hope it helps...
Have a look at a few projects on this forum to get an idea of how people are restoring there mk1's.
