??? Eckler's apparently sells a repro clutch hydraulic line that is not bent exactly right for specific fitments. IT sounds like they did some of their own engineering to get people to buy a package.
Any competent heavy equipment shop can build a new hydraulic line for you and so can a brake parts shop. Take the original hose and the new slave cylinder and they can build a hose that works fine and at a whole lot less that what Eckler's charges.
It really steams me when places like Ecklers' preys on Corvette owners like this. It's bad enough that GM discontinued the clutch hose, but to see Eckler's create a replacement hose (and one that doesn't fit right!!) and then say you have to use their hose with a new slave cylinder is just plain wrong.
I have read lots of different complaints and rants about Eclker's and their poor quality control and lack of commitment to customer service that I don't understand why people still buy from them, or for that matter, why they are even still in business. If you compare Eckler's prices with the other accessory and parts catalogs, they are typically 5-10% higher for the same item.
