One of the things about being a 'Bolter is being able to do it yourself. The point of DIY is to save a buck. I know plenty of people who do restorations with deep pockets who would have paid $420 for that tie rod when they could just as easily have got it for $30. They don't care. They got deep pockets!
For those of us on budgets however, we look at prices for parts. As has already been stated, you are responsible for your own research and homework, whether it be parts prices, assembly procedures, or historical accuracy of your vehicle. It's your truck and your experience restoring it!
The best part about stovebolt.com is we share information we learn from our projects.
I am someone who shops around the different vendors, and I have learned to bundle as many parts together as possible. Sometimes we make bad buying decisions; that's part of the learning process.
