Depends on what parts you are talking about and everyone will have different opinions. I've had success with Legendary for interiors, PST for suspension components, Summit for engine/trans parts, The Mopar Shop for body parts, and Year One for just about anything and I start with them if the price is comparable. These selections were completed prior to me joining this forum, so now I would focus on doing business with those that belong to this site. Oh, and I did use Just Dashes and while it was "spendy" ($1,000) and took a while, it is freakin' amazingly perfect! I'm also restoring a 66 Ford Galaxy 500xl convertible (wife's) and have used the same companies for similar components and have been satisfied. But I'm just a weekend warrior, other guys do this for a living so I'm interested to see their opinions.
