Question to the past successful frame off restoration guys.

[Bubba4spd]

Approx. how much more money and time does it take to actually complete a project than you projected it would in the beginning? I have a 68 swb that I would love to dive into but it does need a lot of work and I know to fully enjoy driving it, I will need to upgrade the 3 spd manual to a 5, and of course 5 lug patter, air, power steering etc. From reading through build threads, several years to complete is not uncommon.
