I follow the philosophy of all or nothing. Its not worth your time to buy tools if you don't plan on doing all future repairs yourself and have the space. Also, this job will likely only be done once as it doubtful you will still have or use the truck by the time this all wears out again.
It is threads like these that make me thankful for all that I have. A few years ago I built a 3 car shop in my fenced off back yard, have a 2.5 car extra deep garage, and about 1000sq ft of space for storage of parts. There are very few jobs I can't do, and I should be getting a lathe that will be housed in a small building that also is my gym.
