Already did that route and have them too. I had them made exactly as the stock ones except add 1" to the overall length of the short cable. Well they added 1" to the long cable instead of the short cable. The short cable the same length as the stock one, except when they made the short cable it was made incorrectly and will no contract enough between the transmission and the crossover pin to access 5th gear and reverse.
I am not sure whether David at http://www.push-pull.com will take this cable back since I've had them for quite a while now or I will just have to have another short cable made. The only problem is that the stock cable they used to make it is now on the car. It was hard enough to try and locate the longer cables originally. I really need to locate another 4446854 or 4504338 cable to have a duplicate made "correctly" this time.
