Check out the link that Carson Dyle provided, Frank. It's got a lot of info included that you'll prolly find interesting.
Custom Replica's is selling castings of the detailing parts - most of which are just hard to find, while others are nigh-impossible to find - as "sets". They're a bit pricey for us "small scale guys", but if you're out to make a SS battlestar, they're a Godsend as, from all I've read, you'll likely save a good 40% to 50% on what it would cost you to pick up those parts individually - which often means multiple kits for pretty rare kits that go for $100+ each on eBay. Even if you buy just one of those kits and make castings, you'll still have to shell out funds for the rubber for molds and resin to make the castings. CR has them already for you to order and then it's up to you to take it the next step.
