How to plan...

i always start out by writing on a piece of in fender tag format and build sheet format the options i want....if its something custom then i make up a code for it......thats how the factory built our cars, as its coming up the line they look at the printout and and put the parts specified.

i would assemble the car completely with all the parts that are going to be permanant and do mods at that time ...that way all bolts are there ...everything fits ....then i disasseble again after everything is complete and fits and start resto

you dont want to be doing mods and changing things after the paint has started to fly
